WebFixed Point Arithmetic ¶ Because fixed-point representation is so strongly related to integer representation, we are able to express arithmetic operations on fixed-point numbers in terms of integer operations. Let’s first derive a few basic rules. We’ll first make the derivation for unsigned numbers. Addition ¶ 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 north aishashire
