tanh

Name

tanh, tanhf, tanhl
- hyperbolic tangent functions

Library

libm.lib

Synopsis

#include <math.h>

double tanh (double x);

float tanhf (float x);

long double tanhl (long double x);

Return values

The tanh, tanhf and tanhl functions return the hyperbolic tangent value.

Detailed description

The tanh and tanhf functions compute the hyperbolic tangent of x. tanhl is an alias to the function tanh.

Examples

#include <math.h>
int main( )
{
   double inp = 1.0;
   double y; 
   y = tanh( inp );
   printf( "tanh( %f)  = %f\n", inp,  y );
   y = tanhf( inp);
   printf( "tanhf( %f) = %f\n", inp, y );
   y = tanhl( inp);
   printf( "tanhl( %f) = %f\n\n", inp, y );
   inp = 2209.0;
   y = sqrt( inp);
   printf( "sqrt( %f)  = %d\n", inp,  y );
   y = sqrtf( inp);
   printf( "sqrtf( %f) = %d\n", inp, y );
   y = sqrtl( inp);
   printf( "sqrtl( %f) = %d\n", inp, y );
}

Output

tanh ( 1.000000 ) = 0.7615941
tanhf( 1.000000 ) = 0.7615941
tanhl( 1.000000 ) = 0.7615941
