Biased Representation(IEEE FP Standard)

• The ‘bias’ 127 represents 0

• 128 to 255 represent positive exponents

• 1 to 127 represent negative exponents

  • (remember 0 is reserved for the entire number being zero).

• The actual exponent is therefore:

  • E - bias

• (-1)S * (1 + significand) * 2E-bias
