Why Swift is so complicated?

Code Block 	let current = 75, total = 100
	let calc:Float = Float(current / total)
	print(calc)

Expected result: 0.75
Console output: 0.0

Swift is not complicated, but you have to take care of its strong typing.

current and total are Int
hence current / total is inferred as Int, and the Int result or 75/100 is 0

Just write:

Code Block let calc : Float = Float(current) / Float(total)

Or declare them as Float:

Code Block let current : Float = 75, total : Float = 100
let calc : Float = current / total
print(calc)
