Hello:

I compiled your code from the command line, with BCC and BCC32 and
the 'equal' word is printed in the console. Then I did a very small
project and compiled from the IDE, getting the result you got,
'not equal'.

Currently I'm working in a POS app, and was getting strange
behaviors related with floating point operations, and the solution
I found to this issue was to use a variable instead a constant,
as in the following code:

int main()
    {
    int Phase = 3;
    double d=3;
    if(Phase/d == 1.0 )
        printf("equal");
    else
        printf("not equal");
    return 1;
    }

Using this workaround yield the expected result when compiled with
the IDE or the command line (16/32 bits).

HTH.

/JJ.
