asinh()

Computes the inverse hyperbolic sine.

  #include <math.h>
  
  double asinh(double x);
  
  float asinhf(float x);
  
  long double acsinhl(long double x);    
Parameter

x

A floating-point value.

Remarks

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

  fpclassifyfpclassify(asinh(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.
