It may seem like humor in retrospect given that Javascript, for example, gives double-precision floating point output for the "%" op. But I don't think it appeared that Javascript would run on billions of devices in the late 90s.

OK, fair, but... by analogy, we might go looking for a Pd object that uses fmod() internally:

 fmod 4
... couldn't create

The specific use case was a demonstration for a class of crossfading between multiple wavetables (in the trendy Massive or Serum softsynth way). The crossfade coefficients are based on fmod(wavetable_index, 2) and really do need the fractional part.

fmod() you can use in [expr], [expr~] and [fexpr~]

And notice in the helpfile of [expr] >> [pd [expr] examples] the use of floats and integers

OK, fair, but... by analogy, we might go looking for a Pd object that uses fmod() internally:

It should have had one.

Would probably be nice to give a suggestion on error for common things like expr functions and other common errors the way git's CLI tools do.

I added a feature request to Purr Data for this:

Edit: and to be clear-- I don't think Pd Vanilla needs to add all the expr functions as internal classes. That could easily cause backwards compatibility issues with externals or private abstraction collections for little benefit.

I know you can multiply-mod-divide and get fractions. The broader point is about usability. It's a difficult trade-off -- adding more features for the sake of usability creates maintenance problems (which, to be honest, we see in SuperCollider-land), but keeping things light and maintainable means that easy things (fmod) become harder than they should be (concrete impact here is, I will have to explain to a classroom full of not particularly technical students why they can't use a simple, dedicated object for floating-point modulo when there are simple, dedicated objects for the other basic operators -- too much fine print gets old after awhile -- or let them use it Purr-Data now, and take it away from them later when I have to switch them to vanilla Pd so that they can use Gem on Mac).
