Correct Answer : 6 digits
The smallest change in a decimal number that can be portrayed by floating-point representation is called precision. The fractional part has exactly 24 bits of implied resolution. Accuracy, on the other hand, is the floating-point number represented by the number of prominent bits in which the range of after decimal is limited.
There are some standards to define very few special floating-point bit pattern zeroes which at the most can have only a single bit hence it can be normalized, the hidden but it is often represented by technique for storing zero.
