The Math.LOG2E property represents the base 2 logarithm of e, approximately 1.442:
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).
Math.LOG2EThe following function returns the base 2 logarithm of e:
function getLog2e() {
return Math.LOG2E;
}
getLog2e(); // 1.4426950408889634
