In computer science, a lookup table (LUT) is an array that replaces runtime computation of a mathematical function with a simpler array indexing operation, in a process termed as direct addressing.
The specific syntax rules vary depending on the specific implementation, programming language, or library in use. Additionally, the functionality of regex implementations can vary between versions . Because regexes can be difficult to both explain and understand without examples, interactive websites for testing regexes are a useful resource ...
Rule of inference or transformation rule, a term in logic for a function which takes premises and returns a conclusion; Phrase structure rule or rewrite rule, used in some theories of linguistics "Rule X" elementary cellular automaton, where X is a number between 0-255 characterizing a specific model (e.g. Rule 110) Phonological rule
Rule of three (hematology), a rule of thumb to check if blood count results are correct; Rule of three (mathematics), a method in arithmetic; Rule of three (medicinal chemistry), a rule of thumb for lead-like compounds; Rule of three (statistics), for calculating a confidence limit when no events have been observed
A set of rules can be used to infer any valid conclusion if it is complete, while never inferring an invalid conclusion, if it is sound. A sound and complete set of rules need not include every rule in the following list, as many of the rules are redundant, and can be proven with the other rules.
Microsoft Excel is a spreadsheet editor developed by Microsoft for Windows, macOS, Android, iOS and iPadOS.It features calculation or computation capabilities, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications (VBA).
In calculus, the product rule (or Leibniz rule [1] or Leibniz product rule) is a formula used to find the derivatives of products of two or more functions.For two functions, it may be stated in Lagrange's notation as () ′ = ′ + ′ or in Leibniz's notation as () = +.
This one is very simple. If a rule would prevent you from improving, or preventing harm to, the encyclopedia, then just ignore it. However, be certain that what you are doing would really improve Wikipedia and is not just something that you want to do. Be prepared to justify your actions to anybody with a reasonable objection.
