DESCRIPTION
The log10f4 function
returns the base 10 logarithms for each x.
RETURN VALUE
The function
log10f4 returns
a float vector in which each element is defined as:
- the base 10 logarithm for the corresponding element of x if the
element is not 0, or
- -HUGE_VALF if the value of the corresponding element of x is 0.
- If an element of x is negative, the corresponding element of the
result is undefined.
