SQRT1_2 (Math.SQRT1_2 property)

public static SQRT1_2 : Number
A mathematical constant for the square root of one-half, with an approximate value of
0.7071067811865476.
Availability: ActionScript 1.0; Flash Player 5 - In Flash Player 4, the methods and properties
of the Math class are emulated using approximations and might not be as accurate as the non-
emulated math functions that Flash Player 5 supports.
Example
This example traces the value of
trace(Math.SQRT1_2);
// Output: 0.707106781186548

SQRT2 (Math.SQRT2 property)

public static SQRT2 : Number
A mathematical constant for the square root of 2, with an approximate value of

Availability: ActionScript 1.0; Flash Player 5 - In Flash Player 4, the methods and properties
of the Math class are emulated using approximations and might not be as accurate as the non-
emulated math functions that Flash Player 5 supports.
Example
This example traces the value of
trace(Math.SQRT2);
