I don't know if it happens just on my Mac, but since Max 8.3.0 there is a bug in the [scale] object.

Fed by integers 0-127, [scale 0 127 0 127] does not output the numbers

17 21 25 29 34 42 50 58 68 84 100 and 116 (always the same numbers).

Setting the exponential value to 1. does not help.

See attached test patch.

Same happens if I try with floats.

happens here too, max 8.3 and 8.21 Win10, It works right with gen scale.

Indeed, it's strange that the gen and standard versions of [scale] don't agree.

That said, comparing floating-point numbers with [==] is always a bit touchy. In your patch, you use an integer version of [==], so, the floating point numbers are first floored then tested (so, 16.9999 becomes 16 which is compared to 17).

Still, you're right, it looks like [scale] has a slight problem.

We are aware of and tracking the scale bug, which was present in Max 8.2.1/8.2.2 as well. 

Sorry to deliver a sloppy testing patch ;-)

I tested also with floats and without rounding the bug was the same, basically.

Cycling'74 agreed after I sent them the bug report.

BTW, [zmap] works, if someone can use it as a temporary replacement.
