Nettetnumbers that is fixed point and floating point. This paper compares the original CORDIC for sine-cosine generation on the basis of their area for 16-bit, 24-bit and 32-bit fixed point numbers. The advantage of floating-point representation over fixed-point (and integer) representation is that it can support a much wider range of Nettet3. feb. 2024 · We note that the integers 0 and 1 (only) are the same in binary and decimal. So we take the example x = .642 base 10. Multiply by 2, and we get 2 * .642 = 1.284. It is to be noted that when we "carry" a digit in base 10 multiplication, 2 times a digit from 1 to 9, the highest result is 18 so the "carry" to the units place will always be 0 or 1 ...

Output = A*B >> 14; A rounding step is needed to get the nearest value.

NettetFixed-point variables have a limited range for the same reason they have limited precision — because digital systems represent numbers with a finite number of bits. As a general example, consider the case where an integer is represented as a fixed-point word of size ws.
