Math.LOG2E

The Math.LOG2E static data property represents the base 2 logarithm of e, approximately 1.443.

function getLog2e() {
  return Math.LOG2E;
}

console.log(getLog2e());
// Expected output: 1.4426950408889634

Value

$$\mathtt{Math.LOG2E} = \log_2(\mathrm{e}) \approx 1.443$$

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:

function getLog2e() {
  return Math.LOG2E;
}

getLog2e(); // 1.4426950408889634
