I have a FBSD 9.3 desktop that supplanted a Linux FC14 desktop used for 
web access, some light development, & other day-to-day tasks (i.e. my 
daily driver, so to speak). I had a bunch of shell scripts written to 
use Linux sh, which was in fact bash, which means it had a superset of 
the arithmetic operators that traditional sh had. When I use these 
scripts under sh under FBSD 9.3, they largely work, though there are 
some minor differences (empty strings evaluate to zero (0) under bash, 
error under sh). The man page for sh doesn't reflect some of these 
compatibilities/incompatibilities, & is a bit short on its description 
of arithmetic evaluations in general. It would be sweet if it were 
updated to document more of the differences/similarities w/ bash, since 
there a clearly a decent number of similarities, & only a few (for me) 
differences. TIA ....
