check if number is within range problem

[Nikiwonno]

The following if statement goes through even though 3.3456 is bigger than 3, it should have been false, can any kind soul explain why the check is not working correctly?

Code: Select all

r::

if((3.3456 between 1 and 3)){
debug := 3.456 " between " 1 " and " 3 
			
		Send {Enter}
		Send %debug%
		}

If with parentheses uses expression syntax, but the If...between docs say:

The "between" operator is not supported in expressions. Instead, use If statements such as if (Var >= LowerBound and Var <= UpperBound) to simulate the behavior of this operator.

Alternatively, follow the If...between syntax shown in the examples in the docs. (Hint: the first parameter needs to be a variable name - a literal number wouldn't work, afaics (at least not as you'd probably expect )).
Using expression syntax would be more future-proof, though, if we look at AHK v2, and is generally recommended.

PS: One-True-Brace style is also not supported by If... between. So you can't have an opening brace ({) on the same line. No problems with this, if you use if (expression) syntax.

Code: Select all

A := new biga() ; requires https://github.com/biga-ahk/biga.ahk

A.inRange(3.3456, 1, 3)
; => false
