bool to int cast

[MathWizard]

Hi all,

I was wondering how the cast from bool to an integer is defined. I guess
that 'false' always leads to '0', but I'm not sure that 'true' always
leads to '1'. Is it possible that 'true' casts tot something like
'non-zero' and thus can take any positive value?

No, int(true) is always 1. And int(false) is always 0.

From bool to int, false is always 0, true is always 1.
From int to bool, 0 is always false, anything other than 0 is true.
