asinh(), asinhf(), asinhl()

Compute the inverse hyperbolic sine

Synopsis:

#include <math.h>

double asinh( double x );

float asinhf( float x );

long double asinhl( long double x );

Arguments:

x

The value for which you want to compute the inverse hyperbolic sine.

Library:

libm

Use the -l m option to qcc to link against this library.

Description:

These functions compute the inverse hyperbolic sine of x.

Returns:

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

Examples:

#include <stdio.h>
#include <math.h>
#include <stdlib.h>

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

produces the output:

0.481212
