Re: [integer division]

[Karl-Friedrich R. <mai...@gm...>]

As gnuplot is not a programming language, i think changing the
integer division behaviour is well permissible for a major version.
And for those who, like myself, misuse gp for general data
evaluation and programming, i´d just say "Suck it up!" ;-)

One should however set up a few extra warnings (probably in the gp
startup messages?), so everybody will catch up on it.


I would like to have an explicit integer division symbol, like e.g.
pascal "div". It´d be faster, could be overloaded to also accept a
real divided/divisor, and just be syntactically clear.

(btw., would it be possible to overload modulo "%" to also accept
reals?)

The problem then persist: Most everybody sometimes forgets the dot
after a number that is supposed to be a real, and then spends half
an hour searching for the bug.
