Back # Math.SQRT2

The ** Math.SQRT2** property represents the square root of 2, approximately 1.414:

$$\backslash mathtt\{\backslash mi\{Math.SQRT2\; =\; \backslash sqrt\{2\}\; \backslash approx\; 1.414$$

Because `SQRT2`

is a static property of `Math`

, you always use it as `Math.SQRT2`

, rather than as a property of a `Math`

object you created (`Math`

is not a constructor).

`Math.SQRT2`

The following function returns the square root of 2:

function getRoot2() { return Math.SQRT2; } getRoot2(); // 1.4142135623730951
