atanh(), atanhf(), atanhl()
Compute an inverse hyperbolic tangent
Synopsis:
#include <math.h> double atanh( double x ); float atanhf( float x ); long double atanhl( long double x );
Since:
BlackBerry 10.0.0
Arguments:
- x
- The value for which you want to compute the inverse hyperbolic tangent.
Description:
These functions compute the inverse hyperbolic tangent (specified in radians) of x.
Returns:
The inverse hyperbolic tangent of x.
Examples:
#include <stdio.h>
#include <math.h>
#include <stdlib.h>
int main( void )
{
printf( "%f\n", atanh( 0.5 ) );
return EXIT_SUCCESS;
}
produces the output:
0.549306
