Math.LN2
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The Math.LN2 static data property represents the natural logarithm of 2, approximately 0.693:
Try it
function getNatLog2() {
return Math.LN2;
}
console.log(getNatLog2());
// Expected output: 0.6931471805599453
Value
Property attributes of Math.LN2 | |
|---|---|
| Writable | no |
| Enumerable | no |
| Configurable | no |
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:
js
function getNatLog2() {
return Math.LN2;
}
getNatLog2(); // 0.6931471805599453
