Q. Explain Fixed Point Representation?

The fixed-point numbers in binary has a sign bit. A positive number has a sign bit 0 whereas negative number has a sign bit 1. In fixed-point numbers we presume that position of binary point is at end that is after least significant bit. It means that all represented numbers will be integers. A negative number can be signified in one of the below ways:

  • Signed magnitude representation
  • Signed 1's complement representation
  • Signed 2's complement representation

(Assumption: size of register = 8 bits including sign bit)
