The way to implement SQRT in go language _golang

This article illustrates the way the go language implements sqrt. Share to everyone for your reference. The implementation methods are as follows:

Copy Code code as follows:

Package MyMath
Import "Math"
Func invsqrt (x float32) float32 {
var xhalf float32 = 0.5*x//Get bits for floating VALUE
I: = Math. Float32bits (x)//gives initial guess y0
i = 0x5f375a86-(i>>1)//convert bits back to float
x = Math. Float32frombits (i)//Newton step, repeating increases accuracy
x = x* (1.5-xhalf*x*x)
x = x* (1.5-xhalf*x*x)
x = x* (1.5-xhalf*x*x)
Return 1/x
}

I hope this article will help you with your go language program.
