2015-02-10math/big: implemented Frexp, Ldexp, IsInt, Copy, bug fixes, more testsRobert Griesemer
- Frexp, Ldexp are equivalents to the corresponding math functions. - Set now has the same prec behavior as the other functions - Copy is a true assignment (replaces old version of Set) - Cmp now handles infinities - more tests Change-Id: I0d33980c08be3095b25d7b3d16bcad1aa7abbd0f Reviewed-on: https://go-review.googlesource.com/4292 Reviewed-by: Alan Donovan <adonovan@google.com>
2015-02-09math/big: API cleanupRobert Griesemer
- better and more consistent documentation - more functions implemented - more tests Change-Id: If4c591e7af4ec5434fbb411a48dd0f8add993720 Reviewed-on: https://go-review.googlesource.com/4140 Reviewed-by: Alan Donovan <adonovan@google.com>
2015-02-06math/big: handling of +/-Inf and zero precision, enable zero valuesRobert Griesemer
- clarified representation of +/-Inf - only 0 and Inf values can have 0 precision - a zero precision value used as result value takes the max precision of the arguments (to be fine-tuned for setters) - the zero precision approach makes Float zero values possible (they represent +0) - more tests Missing: Filling in the blanks.
