casin(3M) Mathematical Library Functions casin(3M)NAME
casin, casinf, casinl - complex arc sine functions
SYNOPSIS
c99 [ flag... ] file... -lm [ library... ]
#include <complex.h>
double complex casin(double complex z);
float complex casinf(float complex z);
long double complex casinl(long double complex z);
DESCRIPTION
These functions compute the complex arc sine of z, with branch cuts
outside the interval [ −1, +1 ] along the real axis.
RETURN VALUES
These functions return the complex arc sine value, in the range of a
strip mathematically unbounded along the imaginary axis and in the
interval [ −pi/2, +pi/2 ] along the real axis.
ERRORS
No errors are defined.
