NAME

cexp, cexpf, cexpl — complex exponential functions

SYNOPSIS

Math Library (libm, -lm)
#include <complex.h>

double complex
cexp(double complex z);

float complex
cexpf(float complex z);

long double complex
cexpl(long double complex z);

DESCRIPTION

The cexp(), cexpf() and cexpl() functions compute the exponential of z.

If z = x + iy, then

cexp(z) = exp(x) cos(y) + i exp(x) sin(y).

RETURN VALUES

The cexp(), cexpf() and cexpl() functions return the exponential of z.

SEE ALSO

clog(3), cpow(3)

STANDARDS

The cexp(), cexpf() and cexpl() functions conform to ISO/IEC 9899:1999 (“ISO C99”).
