# Math.SQRT1 2

## Math.SQRT1 2

The Math.SQRT1_2 property represents the square root of 1/2 which is approximately 0.707:

$Math.SQRT1_2=12=12≈0.707\mathtt{\mi{Math.SQRT1_2 = \sqrt{\frac{1}{2 = \frac{1}{\sqrt{2 \approx 0.707$

## Description

Because SQRT1_2 is a static property of Math, you always use it as Math.SQRT1_2, rather than as a property of a Math object you created (Math is not a constructor).

## Examples

### Using Math.SQRT1_2

The following function returns 1 over the square root of 2:

function getRoot1_2() {
return Math.SQRT1_2;
}

getRoot1_2(); // 0.7071067811865476
