推 Bearcome:3就是2^-149啊= = 01/24 11:39

(a)Which is(are)correct?
i.Suppose there was a 16-bit IEEE 754-like floating-point format with 5
exponent bits.
(±1.0000 0000 00*2^-15 to ±1.1111 1111 11*2^14, ±0, ±∞, NaN) is the likely
range of
numbers it could represent.
ii.For a 32-bit IEEE 754 floating-point standard, the smallest positive
normalized number is:
1.0000 0000 0000 0000 0000 000*2^-125
iii.For a 32-bit IEEE 754 floating-point standard, the smallest denormalized
number is:
0.0000 0000 0000 0000 0000 001*2^-126
應該是無解吧
I.2^-15改為2^-14 2^14改為2^15
II.2^-125改為2^-126
III.2^-126改為2^-149 因為2^-126x2^-23=2^-149
是這樣嗎? 老師的答案是III
