Compute the inverse hyperbolic sine

Synopsis:

#include <math.h>

double asinh( double x );

float asinhf( float x );

Library:

Description:

These functions compute the inverse hyperbolic sine of x.

Returns:

The inverse hyperbolic sine (specified in radians) of x.

int main( void )
{
    printf( "%f\n", asinh( 0.5 ) );
    return EXIT_SUCCESS;
}

produces the output:
