What is 1.0,2.0&1/2 in hex?
1.0=(−1)0×2(127−127)×1.0
Therefore, s=0,e=01111111,f=00000000000000000000000
bin: 00111111100000000000000000000000
hex: 3 f 800000
2.0=(−1)0×2(128−127)×1.0
Therefore, s=0,e=10000000,f=00000000000000000000000
bin: 010000000100000000000000000000000
hex: 40000000
1/2=(−1)0×2(126−127)×1.0
Therefore, s=0,e=01111110,f=00000000000000000000000
bin: 00111111000000000000000000000000
hex: 3f00 0000
