There are at least 3 problems I see:
1. When rounding a continuous sequence of digits that don't terminate before
the first digit (eg. 999^-4 to 2 decimal places), the have_int variable is
incremented, instead of the exponent variable.
2. Even with 1 fixed, the exponent is ignored when printing the digits before
the decimal place, so we get no digits or wrong digits (0.9 + #.### = .900,
0.09999 + #.### = 1.000). (There's some variable called pad that might be the
'exponent' before the decimal point?)
3. The trailing zeroes should be discarded but aren't.
