CASINH(3)             DragonFly Library Functions Manual             CASINH(3)

NAME
     casinh, casinhf, casinhl -- complex inverse hyperbolic sine

SYNOPSIS
     #include <complex.h>

     double complex
     casinh(double complex z);

     float complex
     casinhf(float complex z);

     long double complex
     casinhl(long double complex z);

DESCRIPTION
     The casinh(), casinhf() and casinhl() functions compute the complex
     inverse hyperbolic sine of z.

     For all complex floating-point numbers z,

           casinh(z) = -i casin(iz).

RETURN VALUES
     The casinh(), casinhf() and casinhl() functions return the complex
     inverse hyperbolic sine of z with imaginary part in the interval [-Pi/2,
     Pi/2], and unbounded real part.

SEE ALSO
     cacosh(3), catanh(3)

STANDARDS
     The casinh(), casinhf() and casinhl() functions conform to ISO/IEC
     9899:1999 (``ISO C99'').
