Math.LN10

The Math.LN10 property represents the natural logarithm of 10, approximately 2.302:

$$\mathtt{\mi{Math.LN10}} = \ln(10) \approx 2.302$$

Description

Because LN10 is a static property of Math, you always use it as Math.LN10, rather than as a property of a Math object you created (Math is not a constructor).

Examples

Using Math.LN10

The following function returns the natural log of 10:

function getNatLog10() {
  return Math.LN10;
}

getNatLog10(); // 2.302585092994046
