In the standard IEEE 754 single precision floating point representation, there is 1 bit for sign, 23 bits for fraction and 8 bits for exponent. What is the precision in terms of the number of decimal digits?
- A. 5
- B. 6
- C. 7
- D. 8
Answer: C. 7
Explanation: Precision is approximately $\log_{10}(2^{24}) \approx 24 \times 0.301 \approx 7.22$. So, about 7 decimal digits.
