Summary description: Long division arithmetic problems
Announcement text: ----------------------------------------------------------------------
Does long division. The dividend must be a positive decimal number and the divisor must be a positive INT. Correctly handles repeating decimals, putting a bar over the repeated part of the decimal. Handles dividends up to 20 digits long gracefully (though the typeset result will take up about a page) and dividends between 20 and 60 digits long slightly less gracefully.
Defines macros longdivision and intlongdivision. Each takes two arguments, a dividend and a divisor. longdivision keeps dividing until the remainder is zero, or it encounters a repeated remainder. intlongdivision stops when the dividend stops (though the dividend doesn't have to be an INT).
longdivision also has an optional argument max_extra_digits. If max_extra_digits is 0, the behavior is like intlongdivision, whereas if max_extra_digits is greater than 60, the behavior is the same as longdivision without the optional argument. In general, longdivision won't add more than max_extra_digits. It might be prudent to use this optional argument if you are computing, say, 1/97 which has a 96 digit period (longdivision will stop anyways to avoid overfull boxes, but the result might not be ideal).
intlongdivision behaves similarly to the longdiv command defined in longdiv.tex, though I think intlongdivision looks better, and it can handle much larger dividends and divisors (the dividend is only constrained by the size of the page, and the divisor can be up to 8 digits long).
