Hello,

I see that the float values become erroneous beyond certain value of 10^10. Why is this happening? What is the reliable range for float.

They aren't infinite precision. You only get 8 or so digits. The actual limits should be in float.h. Try a double.

It is not the case that all integer values can be exactly represented in floating point representation. Your code shows one integer value that cannot be exactly represented in the type float. For more background, perform an internet search on the term can all integers be exactly represented in float.

Thanks and regards,
