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).

Is fixed-point arithmetic faster?
Integers and fixed-point arithmetic in FPGA
In other words, 10 out of the 16 bits are used to represent the fractional part and 6 bits for the integer part. Fixed-point arithmetic is widely used in FPGA-based algorithms because it usually runs faster and uses fewer resources when compared to floating-point arithmetic.
What are the different types of fixed-point arithmetic?
There are three parts of a fixed-point number representation: the sign field, integer field, and fractional field.
What is fixed-point arithmetic in embedded C?
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. The purpose of this technique is to use integer arithmetic (int, long...) while being able to represent fractions.
What is a fixed-point set?
set. of a real linear topological space and if M is star-shaped with respect to one of its elements, p, then each closed subset of M which contains p is a fixed point set of M.
