[rules-users] Division Operator in a Rule Condition

[Wolfgang Laun]

Check the "Expert" manual. What you need here is a so-called "Return Value
Restriction" where you relate a field and a parenthesized expression using a
relational operator; i.e.: <field> <op> ( <expr> )

Therefore, $b/$c <= 105 is not correct, but $b <= ( 105*$c ) is (apart from
possible truncation if $b and $c are integers).
