eg symbols for 1-9, and 10,20,30,40,50, in the form of eg A,B,C,D,E,F. It's also the same form i use for all alternating bases, eg Mayan. In essence, the numerals stand for the lower row of the abacus, while the letters stand for the upper row. The zero rune reflects actual zero usage. The word UNIX is shuffled around, to represent U,I as the high row, and N,X as the low row. Mayan numbers are read in NUXI, so a number like 1957 becomes 4.17.17, or 4 2C 2C (the dashes, representing the 5's follow the dots. Digits are clearly separated. A quoted value for sqrt2 runs 1B4E1A, of equal spacing, but no head. We see this becomes in modern script as 1:24:51:10. The next digit is 7, in the form 1BE1A 7, where A 7 represents 10:07, not 17. This is not apparent had the digits been written with included zeros. --
2357:"Decimal-encoded" doesn't seem to describe the Babylonian system (although it may describe the modern form in which Babylonian numbers are written using Arabic numerals). In Babylonian notation the units 1 to 9, and the tens 10 through 50, are each represented as simple tallies using different markers for the units (Y) and tens (<) places. However, the resulting combined numbers in the range 1 to 59 are used in a sexagesimal place value system. I don't know if there is a simple term to describe such a hybrid system of notation and I'll leave it to the experts on mathematical terminology to sort that out. 95: 85: 64: 31: 510:
that symbol), is written either leading or medially (so 1 second might be written as 001, or 0:0:1, assuming the unit degree, or 0:0:0:1 (the sextant). One could write 61 as 11 and 3601 as 101. In the first example, there is a missing 10, so this is skipped (the instruction is to put 1 stone in a column unit, and the next in the next column unit). There is no symbol for a semimedial zero (ie D 1 vs D1, ie :D:1: = 40.01 vs :D1: = 41, but this is no great miss.
3705:"Contrary to a widespread belief the sexagesimal system did not originate from any astronomical concept. Its beginnings go back to the earliest Mesopotamian civilization, more than a millennium before any computational astronomy existed. Its origin can be found in the norms for weights and measures in combination with palaeographical processes which led to the place value notation which is the most characteristic element of this number system." 1541:
has too small fonts for the fractions, whereas version 1 makes them all equal to the text size (in the MathJax rendering), and the horizontal spacing in version 2 is also bad (too tight in the sexagesimal part and too little space before the third plus sign and the equal sign). And as a general matter of principle, converting something that works with MathJax to something that doesn't is moving in the wrong direction. —

Maybe save the decimal for articles linked to time measurment, instead of pure mathematics? Also as it's a multiple of a

A table of reciprocals of the 5-smooth sexagesimal numbers (the ones that have finite representations) is already in the article, and such tables can be sourced and notable (because the Babylonians made and used them, and because it's useful to know how long an even fraction of an hour or minute is).

About "useful for something" – not really, unless for some reason you want to find out how many minutes and seconds 1/7 of an hour is, since we don't really use sexagesimal any longer (we may use it for time, but I would say we're not fluent in it, or things like 45 sec × 7 = 5 min 15 sec wouldn't be
2411:
The only reason why I don't feel the former is more abnormal is that the hours place isn't sexagesimal, it's quadrovigesimal. Time is not a pure sexagesimal system. So I think both are weird and would write 3 d and 2 d respectively. If there were 60 hours in a day, then I would surely find 72 h weird

I don't know. The babylon use of two digits to represent numbers base 60, is probably no different to the romans using two digits I, V. In practice, if one wants to experiment with the problems and such of the sumerian notation, it is best to do direct transliteration of the digits, viz A=10, B=20,

Lacking a source for the article's extension of modern time notation to sexagesimal numbers in general, I think that, as an encyclopedia, Knowledge should use the comma and semicolon notation that is widely accepted in the scholarly literature, where it is applied to units of time, angle, length, and

Your comment that Babylonian notation didn't distinguish integer and fractional parts of the number may be true (although I'm not certain about later Babylonian texts) but it certainly isn't true for later astronomers using sexagesimal numbers in Greek, Arabic, and Latin. They, like we, wrote digits
618:
The reason for this change is that this is the notation we use when we write hours:minutes:seconds. So it should be much more familiar to readers than some alternative notation involving commas. And it is very far from being unsourceable, because it is a standard notation taught to kids in elementary
427:
Because sexagesimal is actually in standard use today (for instance in showing times as hours:minutes:seconds) and that standard use represents each base-60 digit as a pair of decimal digits. We should be following standard conventions here, not trying to make up new and more logical conventions: see

The Base 62 article uses the 26 uppercase letters and then the 26 lowercase letters to represent numbers greater then 9, why doesn't this article follow along with the pattern by using A-x? It will look a lot better this way, at the moments it’s hard to tell the difference between numbers that are in

One should note that for the greater time, sixty-wise numbers are intended to be a division system, where the unit column is at the left, and more right-places are more precision. For example, 15 hours, 15:00 hours and 15:00:00 hours are all the same thing, going to minutes and seconds respectively.

The sumerian circle for tangable circles, is given in Heath (vol 2, p216), as 180 ells of 24 digits, which gives a circle diameter 60, pi=3. Circles by diameters is how one finds them in the real world (eg circular inch = area of circle 1 inch diam). The division of the circle to 360 degrees comes

Sexagesimal is best thought of as a division-system to avoid division. In sumerian and later, the Most significant digit is the units, the remainder is fraction. One notes in modern parlance, 15 hours and 1500 hours are the same thing. One finds among the tables of the reckoner, the multiples of

Thanks for the reply. As I read it, you seem to be saying that there is no source for the use of this notation except in the limited field of expressing units of time. If that is so, one could equally well argue for extending the familiar angle notation for degrees, minutes, and seconds (° ' ") to

Using either the modern notation (ie columns of 60, with markers), or sixty separate runes for base 60 confuses the issues as presented in sumerian and other records. In practice, the thing is an alternating base, used mainly for division (fractions). A transliteration of the sumerian runes gives,
505:
The use of zero to show sixtyone is wrong. One should remember that any notation is to write the position of stones on the abacus, and that one has either full-value tokens (like C = 100 or $ 1 1c for $ 1.01, or some kind of spacing empty column-marker, like zero. The egyptians had a zero too, but

for an example of what goes wrong when one treats it as a mixed-radious system with alternating bases 6 and 10.

The ancient sumerian use of this system is a division-system (means of writing fractions), designed to avoid the arithmetic division. We note that one of the common tables that come down to us is the table of ordered recriprocals, eg 3 -- 20 3.20 -- 18 etc, one doing general division by way of

I had a comment on the same sentence, so I'll just add it to this section: my thinking is, "60 is the smallest number that is divisible by every number from 1 to 6" does not get to "the point"; 60 is the smallest number divisible by 3, 4 & 5 is what is important. divisibility by 6 is a "nice to
2415:
When adding and subtracting in sexagesimal, I think of it as a mixed 6-on-10 radix system. When multiplying and dividing, I tend to instead think of it as pure base 60 with two-piece digits, and use Michael DeVlieger's reciprocal divisor method. Both have their respective merits, although I suspect
1075:
I've seen in a number of references a calculation of sixty-number, laid out with the digits evenly spaced, like 3 . 8 3 for 38C (pi) with little regard to the alternation. While this looks strange to people who grew up on a diet of ten-like bases, for people who regularly use alternating bases, it

Zeros in the sumerian system reflect the division system, so they have leading zeros and medial zeros, but not trailing ones: we see eg 0:0:1 for 1 second, and 1:0:1 for 1 hour 1 second, but not 1:0 for 1 hour 0 minutes. One could shift the lead column by changing the unit, eg 1:4 shock is 1.03333

I very much prefer version 2, not only because in my opinion the misalignment is much less noticeable than the overly huge and thick font used in version 1. Version 2 also has other advantages: It actually displays text, therefore it will produce useful display content also with text-only browsers

One can represent sumerian numbers in a notation that matches the written runes: 0, 1-9, and A-F for 10-50. Semicolons are used to indicate columns, are not in the source. There is evidently no confusion between 2 (II) and 1:1 (I I). A zero 0 is written as a full stop (that's the usual meaning of

On my iPhone the disproportion between the font sizes is not quite as bad, with the equation in version one about 1 1/2 times as large as the text font. Considering the fonts used, the font in version two is the same sans serif font as used in body of the text, while the font in version one is a

On my desktop computer (using generic Mozilla Firefox under Windows 7 and with no additional mathematical rendering tools), the equation font in version one is twice the height of the text font and appears quite jarring; in version two there is a slight misalignment between the vertical fractions

you want as many as possible, and we have 5 fingers so you want 5. but wanting as many as possible is tempered by "but the base can get too big", so that's why 7 is not included (420 anyone?). But since 6 comes for free with 3 4 5, it doesn't need to be a reason. 3 4 5 is a tighter explanation.
1576:
No, I believe you are misrepresenting my opinion. The argument that I believe is strongest is that your version looks even uglier than the default bitmap rendering. I find the misalignment much worse than the font size issue. It is not minor. If you want a third opinion, you could try asking at

5832. What makes me think that it is an alternating base, is that one sees calculations where the digits are evenly spaced, like 3 D 5 (for 1/16 = :03:45), where the digits are presented without punctuation. I have seen seven or eight digits of 60 thus represented. It's usually a marker that

Neugebauer also gives the number of the sumerians for the multiplication scale. It's a mixture of units, such as using i (one), x (10), I (60 = big 1) and X (big 10 = 100), along with U (120 = 2*60). A date consistently refered to in the table as 3:12, would elsewhere be written as XIxxii (ie

Perhaps it would be easier to reprensent digits above 9 with the standard lettering aproach used in other number system articles, that is to follow up the digits 1-9 with new digits A-Z and then, in this case, the lowercase letters a-x? I understand that the decimal digit approach is used to

There is no record of the sumerians using a system like this: it's always been alternating symbols from the set 1-9, and A-F (for 10,20,30,40,50). Many of the things that i see written of this system is exactly what one would expect of an alternating-base division system. I use an ordinary

The current version of our article writes that Ptolemy used the value 3;8,30 for π. But this would be simpler written as 6;17 for 2π. Do we have a source indicating whether Ptolemy considered π or 2π as primary? Currently our statement about his value is unsourced.

This is a residue of a vigesimal (base 20 system), in which there are words for 60 and 80, but 70-79 and 90-99, are made by adding the numbers 10 to 19 to 60 or 80. 80 is also 'quatre-vingt' or 4-20, showing more evidence of a vigesimal system.

The Ancient Indians had a sexagesimal system as well; as clearly explained in the Surya Siddhanta. I think there needs to be a paragraph on that. In fact, the two cultures, Sumeria & India, developed the sexagesimal system independently.
