I would like to truncate the result of division , without rounding up,
for report presentation.

Is there such a feature in C and Informix?

If the result is in the range of a long int you can use

long ip;
double a=10.0,b=7.2;
ip= (long)(a/b);

otherwise use the floor command.

(long)(a/b) can also round up if a/b is negative, which ieplved didn't want.
(On the other hand, the question also said "truncate",
so it's not quite clear what's really being asked for)
