Why is SSE scalar sqrt(x) slower than rsqrt(x) * x?
...table, similar to mathematical tables of old, using adjustments to the low-order bits to save on transistors.)
The reason why it's available is that it is the initial estimate used by the FPU for the "real" square root algorithm.
There's also an approximate reciprocal instruction, rcp. Both of these...
New Array from Index Range Swift
... ArraySlice).
Therefore, you can use subscript(_:) with init(_:) in order to get a new array from the first n elements of an array:
let array = Array(10...14) // [10, 11, 12, 13, 14]
let arraySlice = array[0..<3] // using Range
//let arraySlice = array[0...2] // using ClosedRange also wor...
