Implicit type conversions

[ArjailerParticipant]

The Implicit type conversions section in the help states that Any numeric type will be automatically converted to Any numeric type.

However, I’ve got a method which takes doubles, Function AreEqual:Void(expected:Double, actual:Double), and if I try to pass floats in, AreEqual(123.45, 123.45), the compiler compains with “can’t find overload … with argument types (float, float)”.

The same thing happens with other numeric data types, e.g. declared as Long and passing Int.

Am I missing something or have I misunderstood?

This works fine here:

Monkey

Function AreEqual:Void(expected:Double, actual:Double) Print expected-actual End Function Main() AreEqual(123.45, 123.45) End

1 2 3 4 5 6 7 8

Function AreEqual:Void(expected:Double, actual:Double) Print expected-actual End Function Main() AreEqual(123.45, 123.45) End

If you have defined several overloads of ‘AreEqual’ you may have problems if the compiler can’t work out which one you are meaning to call, eg: if you define AreEqual( Double,Double ) and AreEqual( Long,Long ) then you’ll get an error as AreEqual( 123.45,123.45 ) is ambiguous.

Yep – I have a Long overload as you guessed – that’ll be the problem  

I was hoping that I’d just need Double and Long overloads and then could pass in any of the numeric types – something like how C# does it where it’ll implicity convert to “larger” types, but you need to explicity convert to “smaller” types: https://msdn.microsoft.com/en-us/library/y5b434w4.aspx

But it’s not really a problem adding overloads for the other numeric types.

For testing these (and other) functions is there any way to specify a double literal in code? e.g. Java and C# let you use 123.45f for float, 123.45d for double, 123L for long etc.

I’ve sorted it now using generics
