when i compile the following code
float f = 6.3f % 2.1f;
The answer must be 0.0.
but it's not.
but when i try this code
float f = 8.4f % 2.1f;
the answer is 0.0.

There is a loss of precision due to the fact that it can't represent the answer as a power of two. (rather than round, it tells you 2.0999999...). It's representative of the inaccuracy of computers when it comes to floating point numbers.
