The Math.asinh() static method returns the inverse hyperbolic sine of a number. That is,

{{InteractiveExample("JavaScript Demo: Math.asinh()")}}

console.log(Math.asinh(1));
// Expected output: 0.881373587019543

console.log(Math.asinh(0));
// Expected output: 0

console.log(Math.asinh(-1));
// Expected output: -0.881373587019543

console.log(Math.asinh(2));
// Expected output: 1.4436354751788103

Syntax

Math.asinh(x)

Parameters

• x
  • : A number.

Return value

The inverse hyperbolic sine of x.

Description

Because asinh() is a static method of Math, you always use it as Math.asinh(), rather than as a method of a Math object you created (Math is not a constructor).

Examples

Using Math.asinh()

Math.asinh(-Infinity); // -Infinity
Math.asinh(-1); // -0.881373587019543
Math.asinh(-0); // -0
Math.asinh(0); // 0
Math.asinh(1); // 0.881373587019543
Math.asinh(Infinity); // Infinity
