Re: [PD] more help file suggestions for pd 0.47

[Matt Barber]

​% can be different with respect to sign in different implementations of C.
fmod() in C is designed to work with floats.

On my system, -10 [mod 3] and -10 [% 3] in Pd work differently. [mod]
outputs the positive remainder, which is 2, while % outputs the remainder
with the sign of the dividend, which is -1.

[div] and [mod] form a pair.  Given two numbers A and B, B*(A [div B])+(A
[mod B]) = A.  [%] and [/]—[int] should form a similar pair, so -10 [div 3]
should yield -4, while int(-10 [/ 3]) should yield -3.

I _think_ (but am not sure) that "%" works differently on different
CPU architectures.

oh, but I can't see it, so you just did it now, right?

I know they differ for negative values input, never knew why the reason..

expr also has a "%" function that behaves in the same way as the [%]
object, to make things more confusing, a "fmod" function in expr also
behaves in the same was as "%", but for float arguments, and not like
vanilla's [mod]

in max, [%~] (or [modulo~]) will behave the same way as "fmod" in expr,
that is modulo for float arguments, which is also in agreement to pd
vanilla's % - only that pd's is for ints.

With all that, what I mean to ask and say is that I can't see what's wrong
with [%] - the odd one out seems to be [mod].

what do you say?

I put in a sentence to scare users away from "%".  Use "mod" instead :)

howdy, I can see it in the sourceforge you updated the help files, cool.

but in the otherbinops-help.pd I still don't see the [%] object

cheers
