This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
La funcion Math.tanh()
devuelve la hyperbolica tangente de un numero, esto es
Pruébalo
console.log(Math.tanh(-1));
// Expected output: -0.7615941559557649
console.log(Math.tanh(0));
// Expected output: 0
console.log(Math.tanh(Infinity));
// Expected output: 1
console.log(Math.tanh(1));
// Expected output: 0.7615941559557649
Sintaxis
Math.tanh(x)
Parametros
x
-
Un numero.
Devolver valor
La hyperbolica tangente del numero obtenido.
Descripcion
Porque tanh()
es un metodo estatico de Math
, siempre se usa como Math.tanh()
, en lugar de ser un metodo de Math
objeto que creas (Math
no es un constructor).
Ejemplos
Usando Math.tanh()
js
Math.tanh(0); // 0
Math.tanh(Infinity); // 1
Math.tanh(1); // 0.7615941559557649
Polyfill
Esto puede ser emulado con ayuda de Math.exp()
funcion:
js
Math.tanh =
Math.tanh ||
function (x) {
var a = Math.exp(+x),
b = Math.exp(-x);
return a == Infinity ? 1 : b == Infinity ? -1 : (a - b) / (a + b);
};
