Math.LOG10E

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

$$\mathtt{\mi{Math.LOG10E}} = \log_10(e) \approx 0.434$$

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
