Hi Dominique,
I think that for a moment we had the plan to rewrite the if() operator
with the old suntax when it is not available in MuParser. I do not know
if it is really possible, but that is something we can work on. Julien
(Malik), Guillaume, do you remember ?
This is a backward-compatibility issue, though more a MuParser than an
OTB one ;)
Regards,
Julien

Thanks Julien for this answer.
We have tested the syntax :
im1b1!=0 and im2b1!=0 ? 0 : im1b1
It's working
We checked also our muparser libs version
old install we have lbmuparser0debian_1 1.34-2 and libmuparser2
2.2.3-3 => "if" is working
new install we have only libmuparser2 2.2.3-3 => "if" is not working
We tried to find libmuparser0debian_1 1.34-2 to get back the "if"
syntax but it's not anymore in ubuntugis can we find it somewhere else ?
We would like to avoid to modify a substantial number of lines in our
processingchain and to disrup our beginner users
