This might be a very rudimentary question, but I'm playing around with if statements and the following example won't work with error "The compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions". Does anybody know what I'm doing wrong?
let a = 4
let b = 3
let c = 10
let d = 2
if ((sqrt((a - b)^2 + (c - d)^2)) > 100) {
print("Yes")
}
Edit: I understood I made a few mistakes and now got it working with:
var a = 4
var b = 3
var c = 10
var d = 2
var e = (a-b)
var f = (c-d)
var g = (e*e)
var h = (f*f)
var j = Double(g+h)
if (j.squareRoot() > 5) {
print("Yes")
}
Use better types!
import simd
distance([4, 10] as SIMD2<Double>, [3, 2]) > 100
And if you've really got to work with those integers…
public extension SIMD where Scalar: FloatingPoint {
init<Integer: BinaryInteger>(_ integers: Integer...) {
self.init( integers.map(Scalar.init) )
}
}
distance( SIMD2<Double>(a, c), .init(b, d) ) > 100
