Don't understand:
int i, j, r;
r = i % j;

 I don´t know if I understand you correctly but are you trying to
do some divisions out of a string? A bit of code of what you are doing
may help.

if you want real decimal numbers (like 1.23456...) you need to use floats. Either use floats instead of ints or cast them.

float fl_i,fl_j,q;
int int_i,int_j;

q=fl_i%fl_j;
or
q=((float) (int_i))/((float)(int_j));

Hope that's what you want,

Arnon David.

wolv491, please do not edit the question once a dialog has started, it makes it impossible to follow.

>> 5%2 does not =2 it equals 2 etc/etc
It should equal 1

We need to know what it is you are doing.  Can you explain this a little more clearly and/or post some code>

>> correct Quotient responce.
>> Quotient=Int_1%int_2;
pehaps you are mixing up / and %.

/ does division and returns the quotient.  when deailing with ints, it returns only the integer portion fo the quotient, like

5/2 = 2
6/2 = 3
7/2 = 3
8/2 = 4

% does division and returns the remainder.  like

5%2 = 1
6%2 = 0
7%2 = 1

5%3 = 2
6%3 = 0
7%3 = 1
8%3 = 2
9%3 = 0

Is it just me, or does the question title have nothing to do with the question.

And the question itself doesn't make sense.

>I'm going crazy trying to get my
>remainders to display

But your variable is called 'quotient' and you want remainders .. no wonder you're going crazy

>I'M using the right operators but its
>still coming back a whole number.

That is because quotients and remainders ARE whole numbers

>How do I get correct Quotient
>responce.

Which is it .. quotient or remainder?

> Quotient=Int_1%int_2;
> 5%2 does not =2 it equals 2 etc/etc

its not 2 .. it is two .. what does that mean?

All I can thing of is that you REALLY want to divide 5 by 2 and get 2.5 OR you want to get .5

Here's how
int i,j,k;
double d,r;
i = 5;
j = 2;
d = i/(double)j; // d is now 2.5
r = (i%j)/double(j) // r is now .5

OK?
