Description

I was trying to use the new version of the datatool package with an existing file, but I encounter a datatool-base warning that I can't figure out.

Probably it's a misconfiguration setting, but when I browse the user guide, I can't find it out.

I managed to reproduce the warning

Package datatool-base Warning: Can't convert `13.5' to decimal: not a number on
input line 14.

MWE

Download (319B)

\documentclass{article}

\begin{filecontents}[noheader,overwrite]{exemplo.csv}
nome,nota
alice,15
bob,12
\end{filecontents}

\usepackage{datatool}
\DTLsetup{store-datum,default-name=exemplo}
\DTLread{exemplo.csv} 

\begin{document}
\DTLmeanforkeys{exemplo}{nota}{\medianotas}
\medianotas
\end{document}

Evaluation

I'll investigate. There seems to be something wrong with \DTLmeanforkeys. However, the aggregate action seems to work fine, so you could use that instead:

\DTLaction[options={mean},key=nota]{aggregate}
Count: \DTLuse{}.
Mean: \DTLuse{mean}.
Or get: \DTLget[mean]{\medianotas}\medianotas.

Update: Ulrike is correct that it's an expansion issue. The same occurs for similar commands such as \DTLsumcolumn.

Update: now fixed in v3.1. Please allow a few days for it to reach the TeX distributions.
