clog10(3) | Library Functions Manual | clog10(3) |
NAME¶
clog10, clog10f, clog10l - base-10 logarithm of a complex number
LIBRARY¶
Math library (libm, -lm)
SYNOPSIS¶
#define _GNU_SOURCE /* See feature_test_macros(7) */ #include <complex.h>
double complex clog10(double complex z); float complex clog10f(float complex z); long double complex clog10l(long double complex z);
DESCRIPTION¶
The call clog10(z) is equivalent to:
clog(z)/log(10)
or equally:
log10(cabs(c)) + I * carg(c) / log(10)
The other functions perform the same task for float and long double.
Note that z close to zero will cause an overflow.
