In JS at least, there’s a concept of truthiness and falsiness. 0, undefined, null, and a few other non-boolean values are treated as false if used in conditionals and logical operations, while every other value is treated as true. I’m pretty sure python has something similar.
num % 2isn’t a boolean result in any of these languages, so I feel like it would always output “odd”Edit: 0 is false, everything else is true.
All of those languages will convert numbers into booleans, 0 is false, all other numbers are true.
Ah that makes sense.
It doesn’t make sense. I understand it, but it doesn’t make sense.
I agree. If anything it should check if there is a nuumber and 0 is clearly a number.

0 is false in C, Python, and JS. It should work
The joys of dynamic typing.
In JS 0 is the same as False
They are not the same, but 0 can be implicitly converted to false.
What do you get if you do: 0 === false
Explosion?
You’d be surprised.
But seriously, numbers can be used as booleans in an impressive number of languages. Including machine code for almost every machine out there.
