How to make a simple Double by Int split in Swift?

Question

Looking at various posts on this topic, but still no luck. Is there an easy way to do division / conversion when dividing Double (or Float) by Int? Here is a simple example of the return of the playground and the error "Double does not convert to UInt8."

var score:Double = 3.00 var length:Int = 2 // it is taken from some an array lenght and does not return decimal or float var result:Double = (score / length ) 

Answer 1

Passing int to double using var result:Double=(score/Double(length)) What this will do, before calculating the division, it will create a new double variable with int inside parentheses, hence there will be a constructor similar to the syntax.

Answer 2

You cannot combine or use different types of variables together. You need to convert them all to the same type so that you can separate them. The easiest way that I see this happen is to make Int Double. You can do this quite simply by adding ".0" to the end of the whole you want to convert.

In addition, FYI: Floats are rarely used, so if you do not use them for something specific, its also just more liquid to use the more common variables.
