I suppose the scripts may not have been tested for other locales, but just to be 100% - could you check and confirm the output of the below:

printf "%3.3e\n" "4.896071809053199e-2";locale

LC_ALL='C.UTF-8'; printf "%3.3e\n" "4.896071809053199e-2"

Hi @rdlrt

First time I've got invalid number again, after the second command it seems to look fine I think.

Command: printf "%3.3e\n" "4.896071809053199e-2"; Output: 4.896e-02

Any idea what this is happening? Just locale related issue?

Thanks

Yeah - as I mentioned , most of the testing would've occurred using en locales. In your case, I am guessing your locale recognises numbers as comma (v/s decimal). Thus, causing trouble.

A quick fix for you would be to add the below to your $CNODE_HOME/scripts/env file (under User Variables section):

export LC_ALL='C.UTF-8'

So, something like this:

I would think that should make guild tools use C.UTF8 for locale values instead of your system default, thereby not hitting you mentioned

Hi @rdlrt

Yeah, I've changed my system default now to C.UTF-8.

Thanks
