casinh()

Computes the arc value of hyperbolic sine.

  #include <math.h> 
  double complex casinh(double complex x); 
  float complex casinhf(float complex x); 
  long double complex casinhl(long double complex x);

Parameter

x

A complex value.

Remarks

These functions return the hyperbolic arcsine of the argumentargument x. If result of the computation is out of range, these functions set errno to EDOM and

  fpclassify(casinh(x))

returns FP_NAN.

This facility may not be available on configurations of the EWL that run on platforms that do not have floating-point math capabilities.
