Description

FastMath has some issues with special cases such as +0.0 and -0.0.

Here are the double cases so far found:

abs(-0.0) expected:<0.0> but was:<-0.0>
signum(-0.0) expected:<-0.0> but was:<0.0>
asin(-0.0) expected:<-0.0> but was:<0.0>
atan(-0.0) expected:<-0.0> but was:<0.0>
log10(-0.0) expected:<-Infinity> but was:<NaN>
toDegrees(-0.0) expected:<-0.0> but was:<0.0>
toRadians(-0.0) expected:<-0.0> but was:<0.0>
ulp(-Infinity) expected:<Infinity> but was:<NaN>

And float cases:
abs(-0.0) expected:<0.0> but was:<-0.0>
