Description
The
log10 function computes the base-ten logarithm
of x. A domain error occurs if the
argument is negative. A range error may occur if the
argument is zero.
Returns
The
log10 function returns the base-ten logarithm.
Implementation Notes
|
The
log10 function is computed by log10 (e) *
log (x).
|
|
If the argument is zero, then
errno is set to ERANGE,
and -HUGE_VAL is returned.
|
|
If the argument < zero, then
errno is set to EDOM,
and -HUGE_VAL is returned.
