4788495d62 [poincare/parser] -1/2 gives - 1/2 and not -(1) / 2 2019-01-10 11:42:05 +01:00

9709fb66b1 [poincare] When approximating, make a special case for x^(p/q) when the 
complex format is real.

In this case, x^(p/q) might have a real result which is not the
principale angle returned by the standard library

leaves is unreal or undefined. If any leaf is unreal the result is
unreal (unreal > undefined)
