Make int and float separate types #100

Closed giann closed 1 year ago

Avoids runtime coercion and removes ambiguity for the user

giann commented 1 year ago

Actually this would introduce coercion visible to the user that was not before
Buzz is meant to be high level, do we want to expose binary representation to the user?
At the most we could gain a little bit in performance, because the VM won't have to test if a number is an integer or a float

Alternatively we could introduce int and float while still keeping num. Letting the user choose if we wants to deal with the distinction or not.

Comparison operators ignore number type
Other operators don't: 1 + 2.5 is not valid
More explicit
No coercion introduced
A little less smooth for the user
