    Description

    Because LN2 is a static property of Math, you always use it as Math.LN2, rather than as a property of a Math object you created (Math is not a constructor).

    Examples

    Example: Using Math.LN2

    The following function returns the natural log of 2:

    function getNatLog2() {
      return Math.LN2;
    }
    
    getNatLog2(); // 0.6931471805599453
