What is Fixed Integer Subtraction? In contrast to the floating point, a fixed-point number has a decimal point with a fixed position. Each number has a number of bits for the integer part and another number of bits for the fractional part with I integer bits, and f fractional bits, the notation for that representation. Note that the most commonly used technique is to use two-complement if negative numbers are to be represented as well. Thus, there is no explicit sign bit as in floating-point. The resolution of a fixed-point number is dictated by the number of fractional bits, f, and the resolution is 2−f. This is the smallest unit that can be handled using this representation. Addition and subtraction are performed by treating the fixed-point numbers as integers and adding them using standard addition/subtraction. In terms of the bit count of the result. In addition to the fixed-point numbers requires that the binary points of the addends be aligned. Later the addition or subtraction is performed. Fixed-point subtraction is equivalent to addition while making use of the two's complement value for any kind of negative values. In subtraction, the addends must be sign extended to match the length of each other. These worksheets have students work towards mastery of subtraction by having a set subtrahend for all the problems on that page.
