Mathematical Library Functions                          casin(3M)



NAME
     casin, casinf, casinl - complex arc sine functions

SYNOPSIS
     c99 [ flag... ] file... -lm [ library... ]
     #include 

     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 ima-
     ginary axis and in the interval [ -pi/2, ]pi/2 ]  along  the
     real axis.

ERORS
     No errors are defined.
