WebIn this chapter, we are going to learn different how an arithmetic operation of multiplication is performed in computer hardware for fixed point numbers. We will also learn about … To add or subtract two values with the same implicit scaling factor, it is sufficient to add or subtract the underlying integers; the result will have their common implicit scaling factor, can thus can be stored in the same program variables as the operands. These operations yield the exact mathematical result, as long as no overflow occurs—that is, as long as the resulting integer can be stored in the receiving program variable. If the values have different scaling factors, then they m…

WebA floating-point (FP) number is a kind of fraction where the radix point is allowed to move. If the radix point is fixed, then those fractional numbers are called fixed-point numbers. The best example of fixed-point numbers are those represented in commerce, finance while that of floating-point is the scientific constants and values. WebFloating Point Arithmetic •Floating point arithmetic differs from integer arithmetic in that ex-ponents must be handled as well as the magnitudes of the oper-ands. • The exponents of the operands must be made equal for addition and subtraction. The fractions are then added or subtracted as ap-propriate, and the result is normalized.

WebArithmetic operations on floating point numbers consist of addition, subtraction, multiplication and division. The operations are done with algorithms similar to those used on sign magnitude integers (because of the similarity of representation) — example, only add numbers of the same sign. If the numbers are of opposite sign, must do subtraction.
