## How to show decimal coma on Mathematical questions with randomized statements (5.6)

I try to show a decimal comma, instead of point in the following question:

\element{group}{ \FPeval\VQfor{trunc(16+random*10,0)} \FPeval\VQsol{round(1000/VQfor,0)} \FPeval\VQnonA{round(100/VQfor,2)}\begin{question}{questionName}\\ Here come the question \VQfor{} mm? \begin{choiceshoriz} \correctchoice{E= 1:\VQsol} \wrongchoice{E= 1:\VQnonA} \wrongchoice{E= \VQsol:1} \wrongchoice{E= \VQnonA:1} \end{choiceshoriz}\end{question}}

I try to use \def\AMCdecimalPoint{,} in the preamble (as from doc, 5.6.1.2, page 40), but it does not work, it still shows a point.

\def\AMCdecimalPoint{,} only acts on AMCnumericChoices (numerical questions where the student has to code the result), and not on the way vlues calculated with fp are displayed.
You can use siunitx (see eg. RE: QCM avec groupe de questions).
