float exp (float x); |
Floating point exponential function.
exp returns the exponential function of floating point argument x
(i.e. calculates e to the x-th power).
Note: exp will return POSITIVE_INF in a case of overflow, and
zero (unsigned, see ZERO; strange, I expected
POSITIVE_ZERO) in a case of underflow.
