Ok thanks for pointing out the actual decimal precision limit, I get it, according to my understanding of 32-bit floats type.
I was also wondering why this kind of common function isn't implemented in vanilla, in the form of an objet, or even as standardized abstraction (like the list-abs ?) ? Because, it's like everyone has to : - download an external library (and get other extra objects) - or build it's own abstraction which make patch less "standardized" (different names, in/outlets) and subject to errors in conception (like here, not using maximum range). I know this might be a delicate debate, but I feel like this kind of function (like "floating-point random" but one could find other examples) could be provided as abstractions, since it's already useable but anyone who wants to learn can check the inner patch ? Don't want to start a messy troll, but at least IMHO this feature really misses in vanilla, ++ Raphaël 2016-05-31 17:12 GMT+02:00 Matt Barber <[email protected]>: > Your maximum [random] resolution is 2^24.
