WebThe result of any operation on a fixed-point number is typically stored in a register that is longer than the number's original format. When the result is put back into the original format, a rounding method is used to cast the value to a representable number. WebFeb 28, 2006 · use of fixed point data type is used widely in digital signal processing (DSP) and game applications, where performance is sometimes more important than precision.

WebFixed-point is an interpretation of a 2's compliment number usually signed but not limited to sign representation. It extends our finite-word length from a finite set of integers to a finite set of rational real numbers [1]. A fixed-point representation of a number consists of integer and fractional components.
