Retrieve specific value and replace the member index

[J-Rob (John Robinson)]

Hallo dear communiuty,

I need I little help to retrieve a speciefic values from a list and replace with another value.
In specific the only index with a values that have a 0 after the comma (p.e. 0.0xxxx, 0.00xxx, 0.000xxx) must become 1.

Unfortunaltely the matchtext, the retrieveitem and the member index component, they didn’t help me, because I have to leave the original value, without rounding it.

Any advice??

Dear Yoann, thanks for the solution,

Any advice?

This is bug in old grasshopper versions, grasshopper menu: disable Display->Draw Full Names
Or if you want to keep the full names, rename the input of the expression from “variable x” to “x”
