you need to pass the points through an Fx component where the function is:
format("{0:0.0##},{1:0.0##},{2:0.0##}", x.x, x.y, x.z)

where {0} is the place holder for the first variable x.x
0.0## is the desired number format at least 1dp but 3 if significant

Hi,

could you send me this gh-file so i could take a look and find out how it works ?

(sorry, your explanation looks difficult to me - i was never good in math)...

If you cannot open the file all you need to do is to paste this:

format("{0:0.0##},{1:0.0##},{2:0.0##}", x.x, x.y, x.z)

 

into the expression field of the F input of an Fx component.

Hi Christoph,

 

you can use an expression to round to a fixed number of decimals (see attached). 

I should probably add a component specifically for this though.

You'll need 0.8.0050 or newer to open that file.

1. Math > Script > F2

2. Panel > Round (number, decimals)

3. Rename x to number and y to decimals

Looks good, but this would not work with string values from a panel (runtime error: function Round is undefined for parameters: String  double).

send your file and I´ll give it a try.

Best, Peter
