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. VERSIONS These functions first appeared in glibc 2.1.
