Mathematical Library Functions                          csqrt(3M)



NAME
     csqrt, csqrtf, csqrtl - complex square root functions

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

     double complex csqrt(double complex z);


     float complex csqrtf(float complex z);


     long double complex csqrtl(long double complex z);


DESCRIPTION
     These functions compute the complex square root of z, with a
     branch cut along the negative real axis.

RETURN VALUES
     These functions return the complex square root value, in the
     range  of  the  right  half-plane  (including  the imaginary
     axis).

ERORS
     No errors are defined.
