81Uniform distribution (continuous) — Uniform Probability density function Using maximum convention Cumulative distribution function …
82Signed zero — is zero with an associated sign. In ordinary arithmetic, −0 = +0 = 0. However, in computing, some number representations allow for the existence of two zeros, often denoted by −0 (negative zero) and +0 (positive zero). This… …
83Three-way comparison — In computer science, a three way comparison takes two values A and B belonging to a type with a total order and determines whether A < B, A = B, or A > B in a single operation, in accordance with the mathematical law of trichotomy. Machine level… …
84Fourier transform — Fourier transforms Continuous Fourier transform Fourier series Discrete Fourier transform Discrete time Fourier transform Related transforms The Fourier transform is a mathematical operation that decomposes a function into its constituent… …
85List of mathematical functions — In mathematics, several functions or groups of functions are important enough to deserve their own names. This is a listing of pointers to those articles which explain these functions in more detail. There is a large theory of special functions… …
86−0 (number) — −0 is the representation of negative zero or minus zero, a number that, in computing, exists in some signed number representations for integers, and in most floating point number representations. In mathematical terms there is no concept of a… …
87Negative and non-negative numbers — A negative number is a number that is less than zero, such as −2. A positive number is a number that is greater than zero, such as 2. Zero itself is neither positive nor negative. The non negative numbers are the real numbers that are not… …
