The IEEE-754 double-precision format to represent floating point numbers, has a length of _____ bits.
- A.
16
- B.
32
- C.
48
- D.
64
Attempted by 301 students.
Show answer & explanation
Correct answer: D
Answer: 64 bits
Explanation: IEEE 754 double-precision (binary64) uses a total of 64 bits, divided as follows:
1 sign bit
11 exponent bits (stored with a bias)
52 fraction (mantissa) bits
Note: For normalized values there is an implicit leading 1 before the fraction, giving an effective precision of 53 significant bits.
