NettetFixed point means we have a constant number of bits (or digits) to the left and right of the binary (or decimal) point. For example, we might have eight digits to the left of the decimal point and two digits to the right. An example is 23953223.49. You are familiar with representations have two digits to the right. NettetA few notes on fixed point precision When adding fixed point numbers together its important to align their radix points (e.g. you must add 12.4 and 12.4 numbers or even 18.4 + 12.4 + 24.4 will work where the integer portion represents the number of bits in use not the physical size of the integer register declared).
