What is Q format in fixed-point?

Q (number) format is a fixed-point method of coding fractional and whole integers for processing by a computer's CPU or a digital signal processor (DSP). The Q format is used to enable rational number processing by a standard integer hardware arithmetic logic unit (ALU).

What does Q stand for in numbers?

List of Mathematical Symbols. • R = real numbers, Z = integers, N=natural numbers, Q = rational numbers, P = irrational numbers.

What is Q8 format?

Unsourced material may be challenged and removed. The Q notation is a way to specify the parameters of a binary fixed point number format. For example, in Q notation, the number format denoted by Q8. 8 means that the fixed point numbers in this format have 8 bits for the integer part and 8 bits for the fraction part.

How do you add two fixed-point numbers?

The addition of fixed-point numbers requires that the binary points of the addends be aligned. The addition is then performed using binary arithmetic so that no number other than 0 or 1 is used.
