The Math.LOG10E static data property represents the base 10 logarithm of e, approximately 0.434.

{{InteractiveExample("JavaScript Demo: Math.LOG10E", "shorter")}}

function getLog10e() {
  return Math.LOG10E;
}

console.log(getLog10e());
// Expected output: 0.4342944819032518

Value

$$\mathrm{𝙼𝚊𝚝𝚑.𝙻𝙾𝙶𝟷𝟶𝙴}={log}_{10}(\mathrm{e})\approx 0.434\backslash mathtt\{Math.LOG10E\}\; =\; \backslash log\_\{10\}(\backslash mathrm\{e\})\; \backslash approx\; 0.434$$

Description

Because LOG10E is a static property of Math, you always use it as Math.LOG10E, rather than as a property of a Math object you created (Math is not a constructor).

Examples

Using Math.LOG10E

The following function returns the base 10 logarithm of e:

function getLog10e() {
  return Math.LOG10E;
}

getLog10e(); // 0.4342944819032518
