    SYNOPSIS

           #include <complex.h>
    
           double complex csqrt(double complex z);
           float complex csqrtf(float complex z);
           long double complex csqrtl(long double complex z);
    
           Link with -lm.
    
    
    

    DESCRIPTION

           Calculate  the  square root of a given complex number, with nonnegative
           real part, and with a branch cut along the negative real  axis.   (That
           means  that  csqrt(-1+eps*I)  will  be close to I while csqrt(-1-eps*I)
           will be close to -I, if eps is a small positive real number.)
