tanh
Compute the hyperbolic tangent of a number.
Usage
var tanh = require( '@stdlib/math/base/special/tanh' );
tanh( x )
Computes the hyperbolic tangent of x
.
var v = tanh( 0.0 );
// returns 0.0
v = tanh( -0.0 );
// returns -0.0
v = tanh( 2.0 );
// returns ~0.964
v = tanh( -2.0 );
// returns ~-0.964
v = tanh( NaN );
// returns NaN
Examples
var linspace = require( '@stdlib/array/base/linspace' );
var tanh = require( '@stdlib/math/base/special/tanh' );
var x = linspace( -4.0, 4.0, 100 );
var i;
for ( i = 0; i < x.length; i++ ) {
console.log( tanh( x[ i ] ) );
}
