NAME
     casinh, casinhf, casinhl - complex arc hyperbolic sine func-
     tions

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

     double complex casinh(double complex z);


     float complex casinhf(float complex z);


     long double complex casinhl(long double complex z);


DESCRIPTION
     These functions compute the complex arc hyperbolic  sine  of
     z, with branch cuts outside the interval [ -i, ]i] along the
     imaginary axis.

RETURN VALUES
     These functions  return  the  complex  arc  hyperbolic  sine
     value,  in  the  range  of  a strip mathematically unbounded
     along the real axis and in the interval [ -ipi/2,  ]ipi/2  ]
     along the imaginary axis.

ERORS
     No errors are defined.
