0: if f1 is numerically equal to f2.Negative value: if f1 is numerically less than f2.Positive value: if f1 is numerically greater than f2.

How do you compare two float values?

To compare two floating point values, we have to consider the precision in to the comparison. For example, if two numbers are 3.1428 and 3.1415, then they are same up to the precision 0.01, but after that, like 0.001 they are not same.

Can we compare float and double in Java?

Since float and double have different sizes, the representation in both types for a non-representable value are different, and thus they compare as unequal. (The length of the binary string is the size of the mantissa, so that’s 24 for float , 53 for double and 64 for the 80-bit extended-precision float (not in Java).
