Fixed-point arithmetic

In computing, fixed-point is a method of representing fractional (non-integer) numbers by storing a fixed number of digits of their fractional part. Dollar amounts, for example, are often stored with exactly two fractional digits, representing the cents (1/100 of dollar). More generally, the term may refer to … See more A fixed-point representation of a fractional number is essentially an integer that is to be implicitly multiplied by a fixed scaling factor. For example, the value 1.23 can be stored in a variable as the integer value 1230 with implicit … See more Scaling and renormalization Typical processors do not have specific support for fixed-point arithmetic. However, most … See more Explicit support for fixed-point numbers is provided by a few computer languages, notably PL/I, COBOL, Ada, JOVIAL, and Coral 66. They provide fixed-point data types, … See more Various notations have been used to concisely specify the parameters of a fixed-point format. In the following list, f represents the number of fractional bits, m the number of … See more A common use of decimal fixed-point is for storing monetary values, for which the complicated rounding rules of floating-point numbers are often a liability. For example, the open … See more Addition and subtraction 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 … See more Decimal fixed point multiplication Suppose there is the following multiplication with 2 fixed point 3 decimal place numbers.

Fixed Point Arithmetic : Addition and Subtraction

WebAn alternate of overflow is saturation, a technique that caps the most positive or most negative value that can be held in a fixed-point representation. This decreases the highly non-linear overflow effect in DSP. The implementation of saturating arithmetic, however, is more complicated than integer arithmetic.
