Sebb commented on MATH-1269:
----------------------------
[Didn't you just choose a number above? ...]
But yes, one possible code fix is as you suggest, along with a unit test to
show that the number has been properly determined.
> FastMath.exp may return NaN for non-NaN arguments

> I have observed that FastMath.exp(709.8125) returns NaN. However, the
> exponential function must never return NaN (if the argument is not NaN). The
> result must always be non-negative or positive infinity.
