DESCRIPTION
The exp2f4 function
returns a vector of the exponential
for each element in x.
RETURN VALUE
The function
exp2f4 returns
a float vector in which each element is defined as:
- 2 raised to the power of the corresponding element of x.
- On the SPU single-precision element values of the result that are greater
than HUGE_VALF are returned as HUGE_VALF and no error is reported.
