WebAug 17, 2024 · Advantages of Fixed Point Representation: Integer representation and fixed point numbers are indeed close relatives. Because of this, fixed point numbers can also be calculated using all the arithmetic operations a computer can perform on integers. They are just as simple and effective as computer integer arithmetic. WebFixed-Point Arithmetic Addition and subtraction Whenever you add two fixed-point numbers, you may need a carry bit to correctly represent the result. For this reason, when adding two B-bit numbers (with the same scaling), the resulting value has an extra bit compared to the two operands used. a = fi (0.234375,0,4,6); c = a+a
