I'm sorry but i lack an english term for that:
3.14159265 I [round] I 3.142
So i can get the data i get from, let's say [env~], and use it properly with graphics (without jittering them around like hell). And yes, i used average and some basic math and got nice results, but something like the above would be nice as well.
Furthermore i search for a Perlin Noise object or a way to implement it. Perlin Noise is nice.

This works for non-negative numbers:
3.14159265 | [* 1000] | [+ 0.5] | [int] | [/ 1000] | 3.142
For negative numbers, it seems [int] truncates towards 0, which is a bit weird.
Also try
[expr floor($f1,0)]
[expr ceil($f1,0)]
Which reminds me to ask, does anyone know why expr's floor and ceil require two arguments, and would it make sense to allow floor and ceil to work with a single argument only?
" expr: syntax error: function 'floor' needs 2 arguments
error: expr: syntax error ... you might be able to track this down from the Find menu. expr floor($f1) ... couldn't create "

Because of a typo that Orm Finnendahl made in 2002.

Yes, but it wouldn't be backwards-compatible, unless [expr] allows optional arguments, but there's no way to specify that in [expr]'s function table.

it is No 1464539 in the bug-tracker.

Do you really think, we should keep this (bug) for backwards compatibility? BTW, Orm told me once, that it wasn't he who wrote this code.

It's possible. Me, I only looked up the credits in pd/extra/expr~/ .

No, I think that [expr] should get an optional argument feature, which would then allow floor() and ceil() to be redefined to be an either-1-or-2-argument function.

Hi Adrian,
3.14159265 | [* 1000] | [i ] | [/ 1000] | 3.141
(not rounded but actually truncated)
Rounding could be implemented by splitting of the last comma position right of the decimal using a [moses 4] object.
Is this what you are looking for? Otherwise there is a message-lowpass filter in the iemlib or iemabs. [line] is also a good thing to smooth out data.
