Formatting has done something weird. I'll put it in multiple message then :
Hi, Most of my students struggle with multi digits number when given an \AMCnumericChoice answer. When there are some 0 in the first digit(s), most of the time they write in the first available row. For example, they need to write 42 in a 3 rows answer, they write [4] [2] [ ] instead of [0] [4] [2] (or [ ] [4] [2] with `strict=false`). When the answers is asked in vertical mode, there is a `vhead` option, originally design for bit weight, but useful for writing "100, 10, 1" in my case. There is no such option for horizontal answers. Thus, I made something to fit my need, but it's a dirty hack that would probably break things elsewhere.

(I had to remove a lot of trailing `%` for the formatting not to go crazy, some unwanted spaces might appears?)

Maybe the option ignoreblank=true
is for you? This works only in decimal mode (not binary).
You can use it for all questions with \AMCnumericOpts{ignoreblank=true}
at the beginning of the source file.

Sounds very good!
I can't find it in the manual to understand what it does, but it might be exactly what I need.
I'll do some tests!
Thanks.
