What does ~~ do? Like in (~~a?h:a*h)
u/Renaud___

It work as a math.floor. actually there is a difference but i dont remember how exactly

~ is a bitwise not. It flips all the bits in the number to the opposite. Flipping again (~~) puts the bits back to what they were. It works does something similar to floor because it truncates floats to 32-bit integers as part of the operation. (But unlike floor, ~~-2.1 is -2 instead of -3.)
