Fix-point number

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.

Changing fixed point representations is commonly called 'scaling'. If you can do this with a class with no performance penalty, then that's the way to go. It depends heavily on the compiler and how it inlines. If there is a performance penalty using classes, then you need a more traditional C-style approach.

WebApr 8, 2012 · Sorted by: 93. The idea behind fixed-point arithmetic is that you store the values multiplied by a certain amount, use the multiplied values for all calculus, and divide it by the same amount when you want the result.
