> 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>
