acosh

• acosh(x: number): number

• Computes the hyperbolic arccosine of a number.

  Notes

  • The domain of x is restricted to [1,+infinity). If x < 1, the function will return NaN.

  Parameters

  • x: number

    input value

  Returns number

  hyperbolic arccosine (in radians)

  Example

  var v = acosh( 1.0 );
  // returns 0.0

  Example

  var v = acosh( 2.0 );
  // returns ~1.317

  Example

  var v = acosh( NaN );
  // returns NaN
