Robert Griesemer	97bcf049f7	big: added a few missing functions: ... - sign to determine if a value is < 0, == 0, > 0 - abs to compute absolute value - Rat.IsInt to test if a rational number is representable as an integer R=rsc CC=golang-dev https://golang.org/cl/1761042	2010-07-12 16:09:27 -07:00
Evan Shaw	2e00bf9877	big: Improvements to Rat.SetString ... * Allow an exponent part. This is necessary for exp/eval. * Fix a bug for input that had no numbers after the decimal. * In Int.SetString, allow a leading + sign. * In Int.SetString, error if the input is "-" with no number. * In nat.scan, normalize the resulting nat.
