Hello,

1. a simple test with the [scale] object doesn't work:

[5]
|
[scale 0 10 100 200 0]
|
Output number keeps "0"

Does anybody has any idea?

2. actually I want to scale a float number. But after rounding them with [round~] (embedded in [sig~] and [unsig~] still throws following error:

error: scale: no method for 'float'

I'd appreciate your help.

My guess is that you are looking at the GEM object [scale] rather than the one you need. You can just choose not to load GEM, if you don't use it. Other than that, this is a conflict I know a few people have experienced, maybe this should be directed at the -devel list?

Michael, for this simple case you can roll your own scale as

number
|

|
[+ 100]
|
output

[scale] just implements variations on the line y = mx + c with different slope and offset constants.

thank you! I got it work with [maxlib/scale 0 10 100 200 0] as well for floating numbers.
