I am trying to implement the “fast inverse square root” algorithm in Julia: function rsqrt(x::Float32) xₛ = x int32 = reinterpret(UInt32, xₛ) int32 = 0x5f3759df - int32 >> 1 xₛ = reinterpret(Float32, int32) xₛ *= 1.5f0 - x * 0.5f0 * xₛ^2 return xₛ end But the result is defi…

How to convert the binary form of a float to an integer, and vice versa?
