I actually have a solution but it's a bit of a kludge.
My solution is to use regular expression and just drop everything prior to the
decimal position like so:
[temp=. ": 105.1
105.1
". '0', temp }.~ {.,'\.' rxmatch temp
0.1
I was hoping that there is another (non-kludge) way.

Unfortunately, the client wants it in the original value (0.1) and not the
expanded value (0.0999999999999996). :(

0.0999999999999996 is probably a correct floating point representation of 0..1.
Coding a hook is shorter, however:
decimal =: -<.
