Explanation:
Detailed explanation-1: -The main disadvantage of floating point is that the computer has to split its storage space between the mantissa and the exponent. This means that the mantissa can cause rounding errors if not enough room is assigned to it. There has to be a tradeoff between accuracy and the range of numbers that we can represent.
Detailed explanation-2: -First, they can represent values between integers. Second, because of the scaling factor, they can represent a much greater range of values. On the other hand, floating point operations usually are slightly slower than integer operations, and you can lose precision.
