2. Fixed-point arithmetic - Wikipedia

   en.wikipedia.org/wiki/Fixed-point_arithmetic

   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 scaling factor of 1/1000 (meaning that the last 3 decimal digits are implicitly assumed to be a decimal fraction), and the value 1 230 000 can be represented ...

3. Fixed point (mathematics) - Wikipedia

   en.wikipedia.org/wiki/Fixed_point_(mathematics)

   Fixed point (mathematics) Element mapped to itself by a mathematical function. The function (shown in red) has the fixed points 0, 1, and 2. In mathematics, a fixed point (sometimes shortened to fixpoint), also known as an invariant point, is a value that does not change under a given transformation. Specifically, for functions, a fixed point ...

4. Q (number format) - Wikipedia

   en.wikipedia.org/wiki/Q_(number_format)

   Q (number format) The Q notation is a way to specify the parameters of a binary fixed point number format. For example, in Q notation, the number format denoted by Q8.8 means that the fixed point numbers in this format have 8 bits for the integer part and 8 bits for the fraction part. A number of other notations have been used for the same purpose.

5. Computer number format - Wikipedia

   en.wikipedia.org/wiki/Computer_number_format

   Fixed-point formatting can be useful to represent fractions in binary. The number of bits needed for the precision and range desired must be chosen to store the fractional and integer parts of a number. For instance, using a 32-bit format, 16 bits may be used for the integer and 16 for the fraction.

6. Common fixed point problem - Wikipedia

   en.wikipedia.org/wiki/Common_fixed_point_problem

   Common fixed point problem. In mathematics, the common fixed point problem is the conjecture that for any two continuous functions which map the unit interval into itself and which commute under functional composition, there must be a point which is a fixed point of both functions. In other words, if the functions and are continuous and for all ...

7. Continued fraction (non-simple) - Wikipedia

   en.wikipedia.org/wiki/Continued_fraction_(non...

   The roots of this equation are the fixed points of f(z). If the discriminant (c − b) 2 + 4ad is zero the LFT fixes a single point; otherwise it has two fixed points. If ad ≠ bc the LFT is an invertible conformal mapping of the extended complex plane onto itself. In other words, this LFT has an inverse function

8. Fixed-point iteration - Wikipedia

   en.wikipedia.org/wiki/Fixed-point_iteration

   The fixed point iteration xn+1 = cos xn with initial value x1 = −1. An attracting fixed point of a function f is a fixed point xfix of f with a neighborhood U of "close enough" points around xfix such that for any value of x in U, the fixed-point iteration sequence is contained in U and converges to xfix. The basin of attraction of xfix is ...

9. Floating-point arithmetic - Wikipedia

   en.wikipedia.org/wiki/Floating-point_arithmetic

   In computing, floating-point arithmetic (FP) is arithmetic that represents subsets of real numbers using an integer with a fixed precision, called the significand, scaled by an integer exponent of a fixed base. Numbers of this form are called floating-point numbers. [1]: 3 [2]: 10 For example, 12.345 is a floating-point number in base ten with ...
