Fixed point vs integer
http://x86asm.net/articles/fixed-point-arithmetic-and-tricks/ 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 representing fractional values as integer multiples of some fixed small unit, e.g. a fractional amount of hours as an integer multiple of ten-minute intervals. Fixed-point number rep…

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. The bit length is defined as: WebMay 12, 2016 · The formula expresses the difference between the largest, and smallest numbers we can represent with an integer/fractional representation. Consider a simple example, such as 2.2 (where there are 2 integer bits and 2 …

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. As we will see later, fixed point arithmetic is much faster than floating point arithmetic. It All Starts With an Integer Recall that a binary number: 1101012 represents the value: WebThe most notable difference is that the built-in integer data types can only represent whole numbers, while the fixed-point data types also contain information on the position of the binary point, or the scaling of the number. This scaling allows the fixed-point data types to represent both integers and non-integers. There are also slight ...
