When I had some programming courses, the teachers always told us that it was 
VERY BAD practice to test for a negated comparaison.

To write "if(x != 0)" or "if(x <> 0)", depending on the language used, was a 
sure way of failing. Instead, it was MANDATORY to use "if(x)". (x!>y) had to be 
replaces by (x<=y) whenever possible to. And (x !>= y) was an heresy!
