NAME
casin, casinf, casinl - complex arc sine SYNOPSIS
#include <complex.h> double complex casin(double complex z); float complex casinf(float complex z); long double complex casinl(long double complex z); Link with -lm. DESCRIPTION
The casin() function calculates the complex arc sine of z. If y = casin(z), then z = csin(y). The real part of y is chosen in the inter- val [-pi/2,pi/2]. One has: casin(z) = -i clog(iz + csqrt(1 - z * z)) VERSIONS
These functions first appeared in glibc in version 2.1. CONFORMING TO
C99. SEE ALSO
