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).


Using Math.LN2

The following function returns the natural log of 2:

function getNatLog2() {
  return Math.LN2;

getNatLog2(); // 0.6931471805599453
