Math.SQRT2
is a constant and a more performant equivalent to Math.sqrt(2)
.
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).
The following function returns the square root of 2:
function getRoot2() { return Math.SQRT2; } getRoot2(); // 1.4142135623730951
