complex — complex
arithmetic
Math Library (libm, -lm)
#include
<complex.h>
These functions support complex arithmetic in the C math library.
Each of the following double complex
functions has a float complex counterpart with an
‘f’ appended to the name and a
long double complex counterpart with an
‘l’ appended. As an example, the
float complex and long double
complex counterparts of double
cabs(double
complex z) are float
cabsf(float
complex z) and long double
cabsl(long
double complex z), respectively.
