?true=1
true

?false=0
false

?1+false
Type Mismatch

any way to get the numeric value of a boolean short of writing an if-then statement?

Re: convert boolean to int?

There's nothing in the SDK that I'm aware of, but I use a simple immediate if function for this kind of thing...

Function IIf( Condition As Boolean, Result1 As Dynamic, Result2 As Dynamic ) As Dynamic
	If Condition Then
		Return Result1
	Else
		Return Result2
	End If
End Function

Used like...

?IIf( True, 1, 0 )

Re: convert boolean to int?

Yeah, I was just hoping... a few languages let you treat true/false as 1/0, and you can save a few lines of code that way.

I can't test it right now, but I'm pretty sure BrightScript treats 1 and 0 as true and false, but not the other way around.

Re: convert boolean to int?

Ok, just tested, and I can confirm that 0 evaluates to false, and everything else evaluates to true.
