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