v7.9.14

I just found out that if I use the expression: `toInt("F")` this returns integer `0`. Is this a bug or am I missing something?

I’m guessing it’s interpreting F as a shortcut for false?

Heh, nice one, `toInt('T')` is casted to 1 😆

Definitely sounds like a bug to me! Or an unwanted quirky feature at the very least

Huh. Looks like T and F are the only ones that resolve.

EDIT: Besides ‘True’ and ‘False’, of course…

I think this is more quirky unwanted feature than bug. There’s a bunch of weird string to int coercions that work:

“off”, “false”, “f”, “no”, “n” -\> 0  
"on, “true”, “t”, “yes”, “y” -\> 1  
“infinity” -\> some max value for the type
