The J Programming Language, a follow-on to APL that is designed to use standard keyboard symbols, uses <. for floor and >. for ceiling. [53] ALGOL uses entier for floor. In Microsoft Excel the function INT rounds down rather than toward zero, [ 54 ] while FLOOR rounds toward zero, the opposite of what "int" and "floor" do in other languages.
Displays the parameter wrapped in ceiling symbols. This template is for display, not calculation. Template parameters [Edit template data] This template prefers inline formatting of parameters. Parameter Description Type Status Operand 1 The operand of the ceiling function Example π Line required Examples {{ceil|45.23}} → ⌈45.23⌉ {{ceil|''x''}} → ⌈ x ⌉ {{ceil|{{sfrac|2''a''|''b ...
The following table lists many common symbols, together with their name, how they should be read out loud, and the related field of mathematics. Additionally, the subsequent columns contains an informal explanation, a short example, the Unicode location, the name for use in HTML documents, [1] and the LaTeX symbol.
The second is a link to the article that details that symbol, using its Unicode standard name or common alias. (Holding the mouse pointer on the hyperlink will pop up a summary of the symbol's function.); The third gives symbols listed elsewhere in the table that are similar to it in meaning or appearance, or that may be confused with it;
In the above example, IIf is a ternary function, but not a ternary operator. As a function, the values of all three portions are evaluated before the function call occurs. This imposed limitations, and in Visual Basic .Net 9.0, released with Visual Studio 2008, an actual conditional operator was introduced, using the If keyword instead of IIf ...
Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities. In these contexts, the capital letters and the small letters represent distinct and unrelated entities.
This waitress was terrified when a python fell from the ceiling
The LISP 1.5 Programmers Manual [3] describes a function called intern which either evaluates to an existing symbol of the supplied name, or if none exists, creates a new symbol of that name. This idea of interned symbols persists in more recent dialects of Lisp, such as Clojure in special forms such a (def symbol) which perform symbol creation ...
