What comparison of two same float numbers result in false?

Question

Say
float i = 1.1;
float j = 1.1;

Many a time if (i == j) results in false. Why??

Answer 1

I think its not possible.

Please check your question. Maybe its
float i = 1.1;
double j = 1.1;

And when you compare these 2 , i.e (i == j), the result will be 0 or false.
It involves the concept of the IEEE 754 Standard for storing Floating-Point and Double.

If thats the case, we can have a discussion on that.

Answer 2

In my machine it is working fine.
Can you please share the machine and compiler details ?
