Which of the given number has its IEEE-754 32-bit floating point representation as (0 10000000 110 0000 0000 0000 0000 0000)
- A. 2.5
- B. 3.0
- C. 3.5
- D. 4.5
Answer: C. 3.5
Explanation: Sign bit = 0 (+). Exponent = 10000000 (128). Bias = 127. True Exponent E = 128 - 127 = 1. Mantissa = 1.110... (binary) = 1 + 0.5 + 0.25 = 1.75. Value = 1.75 * 2^1 = 3.5.
