M Math.SQRT1_2 (Constant/static) Math.SQRT1_2 (Constant/static) A mathematical constant value. Availability: ECMAScript edition 2 JavaScript 1.0 JScript 1.0 Internet Explorer 3.02 Netscape 2.0 Netscape Enterprise Server 2.0 Opera 3.0 Property/method value type: Number primitive JavaScript syntax: -Math.SQRT1_2 This constant returns the numeric value of the square root of 0.5. The resulting value returned is approximately 0.707106781186548 (to 15.d.p.) Warnings: . Note that the value of Math.SQRT1_2is approximately the reciprocal of the value of Math.SQRT2. The word approximately is used here, because the mathematical accuracy of JavaScript implementations leaves something to be desired and there are some strange artifacts in some of the calculations.
