Re: [julia-users] overflow behavior

What if numeric literals acted the same way as irrational numbers like pi, and automatically adapted to the environment where they are used? I know that that sort of rule would have made a lot of the bit twiddling code a lot simpler than having to worry that 0xff and 0x1ff, or

[julia-users] overflow behavior
