Addition of FP Numbers

• Given two numbers:

  • normalise them both
  • adjust the floating point of the smaller number to match the larger one
  • Add them together
  • renormalise
  • check for underflow/overflow of exponent
    • if so then break;
  • round significand to required number of bits
    • might need renormalisation (eg, 11111 round to 4 bits).
