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 integer. 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 integer).
\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).
