Math.LOG2E

Summary

The Math.LOG2E property represents the base 2 logarithm of e, approximately 1.442:

$$\mathtt{\mi{Math.LOG2E}} = \log_2(e) \approx 1.442$$

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

Example: Using Math.LOG2E

The following function returns the base 2 logarithm of E:

function getLog2e() {
   return Math.LOG2E
}

getLog2e() // 1.4426950408889634
