Description

Because LOG2E is a static property of Math, you always use it as Math.LOG2E, rather than as a property of a Math object you created (Math is not a constructor).

Examples

Using Math.LOG2E

The following function returns the base 2 logarithm of e:

js
function getLog2e() {
  return Math.LOG2E;
}

getLog2e(); // 1.4426950408889634
