ANSI_SYNOPSIS

#define _GNU_SOURCE

double complex clog10(double complex <[z]>);
|

float complex clog10f(float complex <[z]>);
|
||||
|

|
||||
DESCRIPTION
|
||||
These functions compute the complex base-10 logarithm of <[z]>.
|
||||
<<clog10>> is equivalent to <<clog>>(<[z]>)/<<log>>(10).
|
||||
|
||||
<<clog10f>> is identical to <<clog10>>, except that it performs
|
||||
its calculations on <<floats complex>>.
|
||||
|
||||
RETURNS
|
||||
The clog10 functions return the complex base-10 logarithm value.
|
||||
|
||||
PORTABILITY
|
||||
<<clog10>> and <<clog10f>> are GNU extensions.
