boolean operation priority is not intuitive to me, expected behaviour?

[abakobo]

In the following code I get a result that I'm not used to. The "Not" operator will take priority on the equals "=" operator. This is not intuitive to me (it's like if "If 1=0" would run if 0 means false and 1 means true)

Function Main()

	Local a:=3
	Local b:=4
	
	Print a=b
	Print Not a=b 'should give True? 
	Print Not (a=b)
	
End

Prints:
False
False
True

I'd personally would have expected:
False
True
True

Thanks

Yeah I sort of agree but this is the way 'C' does it so I went with that. Perhaps I should have been a bit bolder here, but it's too late now. To change it would likely quietly break a ton of code due to monkey2's relaxed bool conversions.

Thanks, glad to see Monkey2 behaves as expected! Le sam. 19 janv. 2019 à 00:37, Mark Sibly <notifications@github.com> a écrit :

Just another example, I saw that code in php project:

if (!$try = get_post('try')) {
......
}

or

if (!$f = fopen('life_problem.csv', 'rt')) {
......
}

And in php firstly work =(assign to variable in this case) and then ! (not).

Please, never write such code in any language! :)
