Compute area hyperbolic sine
Returns the area hyperbolic sine of x.

The area hyperbolic sine is the inverse operation of the hyperbolic sine.

Header <tgmath.h> provides a type-generic macro version of this function.
Additional overloads are provided in this header (<cmath>) for the integral types: These overloads effectively cast x to a double before calculations (defined for T being any integral type).

This function is also overloaded in <complex> (see complex asinh).

Parameters

x
Value whose area hyperbolic sine is computed.

Return Value

Area hyperbolic sine of x.

/* asinh example */ #include <stdio.h> /* printf */ #include <math.h> /* asinh, exp, cosh */ int main () { double param, result; param = exp(2) - cosh(2); result = asinh(param) ; printf ("The area hyperbolic sine of %f is %f.\n", param, result); return 0; }

Output:
 The area hyperbolic sine of 3.626860 is 2.000000.
