Use of fixed-point data can … georgetown university applyIn 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.
