Suppose we have a 10-bit computer that uses 10-bit floating point computational unit (Float number uses IEEE floating-point arithmetic where a floating point number has 1 sign bit, 5 exponent bits, and 4 fraction bits). The representation for +∞ (plus infinity) is
In IEEE format, infinity has the exponent field all 1s and the fraction all 0s. The sign is 0 for +∞.
+∞ = 0 11111 0000
(Exponent all 1s with a non-zero fraction means NaN.)
Answer: (D)
