Computers typically compute the square root of x using a loop. Starting with some guess z, we can adjust z based on how close z² is to x, producing a better guess: z -= (z*z - x) / (2*z) Repeating this adjustment makes the guess better and better until we reach an answer that is as close to the actual square root as can be.

func FMA ¶ 1.14 func FMA(x, y, z float64) float64. FMA returns x * y + z, computed with only one rounding. (That is, FMA returns the fused multiply-add of x, y, and z.) func Float32bits ¶ func Float32bits(f float32) uint32. Float32bits returns the IEEE 754 binary representation of f, with the sign bit of f and the result in the same bit position.
