Math.E
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.E
static data property represents Euler's number, the base of natural logarithms, e, which is approximately 2.718.
Try it
function compoundOneYear(interestRate, currentVal) {
return currentVal * Math.E ** interestRate;
}
console.log(Math.E);
// Expected output: 2.718281828459045
console.log((1 + 1 / 1000000) ** 1000000);
// Expected output: 2.718280469 (approximately)
console.log(compoundOneYear(0.05, 100));
// Expected output: 105.12710963760242

Description
Because E
is a static property of Math
, you always use it as Math.E
, rather than as a property of a Math
object you created (Math
is not a constructor).
Examples
Using Math.E
The following function returns e:
js
function getNapier() {
return Math.E;
}
getNapier(); // 2.718281828459045
