WebFeb 10, 2024 · The basic idea behind fixed-point numbers is that even though the values being represented can have fractional digits (aka the 0.23 in 1.23), you actually store the value as an integer. To represent 1.23, for example, you can construct a fixed_point number with scale = -2 and value 123. This representation can be converted to a … 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 Addition and subtraction To add or subtract two values with the same implicit scaling factor, it is sufficient to add or subtract … See more Explicit support for fixed-point numbers is provided by a few computer languages, notably PL/I, COBOL, Ada, JOVIAL, and Coral 66. … See more Various notations have been used to concisely specify the parameters of a fixed-point format. In the following list, f represents the … 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 source money management application GnuCash, written in C, switched from … See more Scaling and renormalization Typical processors do not have specific support for fixed-point arithmetic. However, most computers with binary arithmetic have fast bit shift instructions that can multiply or divide an integer by any power of 2; in … See more Decimal fixed point multiplication Suppose there is the following multiplication with 2 fixed point 3 decimal place numbers.

WebNov 23, 2024 · The term "Fixed-Point" refers to the position of the binary point. The binary point is analogous to the decimal point of a base-ten number, but since this is binary rather than decimal, a different term is used. In binary, bits can be either 0 or 1 and there is no separate symbol to designate where the binary point lies.
