da218e6af7250a97c0ae0439695833fd4a60cdda Guard exp2f_ to never return a negative value
Certain inputs could end up returning -NaN. That would then be used as
input to eval later, and the sign-stripping wouldn't work correctly, so
we'd pass -NaN to powf_, triggering the assert.
Mathematically, exp2f_ should never return a negative value, so clamp
any underflow result to 0.
