LOG10E

Summary

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

Math.LOG10E=log10(e)0.434\mathtt{\mi{Math.LOG10E}} = \log_10(e) \approx 0.434

Property attributes of LOG10E
Writable No
Enumerable No
Configurable No

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

Example: Using Math.LOG10E

The following function returns the base 10 logarithm of E:

function getLog10e() {
   return Math.LOG10E
}

getLog10e() // 0.4342944819032518
