\(1.2.\)Number Representation

1.Binary representation

• We move -1 to the right by one, -2 to the right, etc. Then the two 0s overlap:

2.Bias encoding

• Because the biased number are all start at 0, the MSB doesn't represent the sign anymore. So in floating point, we can compare two biased number directly as if they were unsigned number.

3.IEC standard prefixes
