Math.LN2

The Math.LN2 static data property represents the natural logarithm of 2, approximately 0.693:

function getNatLog2() {
  return Math.LN2;
}

console.log(getNatLog2());
// Expected output: 0.6931471805599453

Value

$$\mathtt{Math.LN2} = \ln(2) \approx 0.693$$

0

Description

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).

Examples

Using Math.LN2

The following function returns the natural log of 2:

function getNatLog2() {
  return Math.LN2;
}

getNatLog2(); // 0.6931471805599453
