How to convert coordinate values of feature and work with list

Hello,

I try to solve two problems. Database in my project contains many types of geometry - points, lines, polygons. I need to do bulk conversion of every coordinate by 2 decimal places. E.g. One point feature has X coordinate 152,125 and Y coordinate 696,745. I need to convert these values to X coordinate 15212,5 and Y coordinate 69674,5. Does anybody idea how to solve this problem please?

Second problem is about work with lists. I have met many times situations when I use list in XML templater. I had to divide values of any attributes in list, so I have to specify index of feature in list, e.g. {fme:get-list-attribute("_indices{0}.x")}. But how can I specify, that I want to put there all values without index 0 please?

Thank You so much!

Lubo

To get from 152.125 to 15212.5 you can use the Scaler transformer (multiply all coordinate values by 100).

For your first question, have a look at the CoordinateRounder.

For your second question you can use the ListExploder and a Tester to filter away the feature where _element_index = 0.

Good catch, didn't see that it wasn't a simple rounding operation.
