Cleaner at least :/

For handling both int and float without conversion you’d need something like this.

[!- 0] and [* -1] ;

the first seems a little bit more efficient even if it is not really significant on my computer.

[!- 0.] and [* -1.] ;

the first is more efficient (about 20%) but due to floating point arithmetic i’m not really sure than result is _exactly_ the same.

Nothing on you, but I cannot stand this type conversion nonsense.

Many thanks for the ! stuff tho, very useful

[expr -$i1] would be much shorter.

-110

It’s not “disgusting,” “nonsense” or “stupid.” It’s just the way it is, and will probably never change, so learn to tolerate it or move on.

Max was just designed with a different set of assumptions than the ones that you seem comfortable with.

I like things to make sense, especially when they’re made by human beings who should know better :). I’ll stop now :).

They are consistent, well documented, and loosely based on older standards for strongly typed languages. (e.g. C, C++)

They just don’t seem to be based on paradigms that you like.

IMHO having to relearn math to learn programming is kind of a bummer.

(if coming from a strongly typed language)

I’d like to have Max be as accessible to non-programmers as possible. I know that’s not in the roadmap, but that’s my preference.
