(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 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 175.180.106.174
