A 32-bit single format number X is divided as shown in Fig.
H.1. The value v of X is inferred from its constituent
fields thus
- 1.
- If e = 255 and , then v is NaN regardless of s
- 2.
- If e = 255 and f = 0, then
- 3.
- If 0 < e < 255, then
- 4.
- If e = 0 and , then (denormalized numbers)
- 5.
- If e = 0 and f = 0, then v = (-1)s0 (zero)
