This file is an overloading of +-*/ operator for Swift, to make it easier to use (and not so strict)
It can make your life with Swift easier when doing calculation between different type. Swift has a type check and requires left operand and the right one the same type. It causes a lot of trouble that we must convert the type every time.
var a = 3 var b = 2.0 a + b //Compile error a - b //Oops, error again a * b //Wtf.. a / b //God please save me //You have to write these instead Double(a) + b Double(a) - b Double(a) * b Double(a) / b
Yes, it is type safe, but it is also time wasted.
Just put the
Easy-Cal.swift to your project, and you can now have a traditional C-like implicit conversion between
Double. So you can write as you would expect without annoying error messages.
var a = 3 var b = 2.0 a + b //5.0 a - b //1.0 a * b //6.0 a / b //1.5
UInt is also implemented, but it seems there is a bug in this beta seed PlayGround, in which there is a fatal error when you assign an
UInt value :(. Fortunately, the
UInt works well in project.
Yes, you lose type safe when using these operators, which is opposite to Swift design. But I find at almost all the time, you will know what you are doing with these numbers and the conversion will be just exactly what you want.
