if and int32 problem
PostPosted: Thu Jun 28, 2007 4:20 am     Reply with quote
Hello All,

I've got problem with if statment. In short description my code looks like this:
Quote:

main()
{
int32 a=-19999;
if (a>9999)
{
do_something_1();
}
if (a<-9999)
{
do_sometging_2;
}
}


When I start program, do_somenthing_1() function is executed every time.

If I change program like this:
[
Quote:

main()
{
int32 a=19999;
if (a>9999)
{
do_something_1();
}
if (a<-9999)
{
do_sometging_2;
}
}


also do_somenthing_1() function is executed every time.

I suppose that problem is in compareing int32 value, but I don't know how to solve this problem. My device is PIC18f4620.

Hello,

In CCS C All types, except float, by default are unsigned.

Try to declare signed int32 a=-19999;

dro.
