In XPath the > operator returns true if the left operand follows the right operand in document order otherwise it returns false. In that regard, it is like the statement sequencing operator in imperative languages, such as the semicolon in C. It is used for sequentially composing two actions, discarding any value produced by the first. In Haskell, the > function is a monadic operator. In C++ it is also used to get input from a stream, similar to the C functions getchar and fgets. In Java, C, and C++, the operator > is the right-shift operator. The double greater-than sign is also used for an approximation of the closing guillemet, ». ASCII does not have the much greater-than sign. The double greater-than sign, >, is used for an approximation of the much-greater-than sign ≫. In Lisp-family languages, > is a function used to mean "greater than". ASCII does not have angular brackets.īASIC and C-family languages (including Java and C++) use the comparison operator > to mean "greater than". The proper Unicode character is U+232A 〉 RIGHT-POINTING ANGLE BRACKET. The greater-than sign is sometimes used for an approximation of the closing angle bracket, ⟩. The Unicode code point is U+003E > GREATER-THAN SIGN, inherited from ASCII.įor use with HTML, the mnemonics > or > may also be used. The text states " Signum majoritatis ut a > b significet a majorem quam b (The sign of majority a > b indicates that a is greater than b)" and " Signum minoritatis ut a is èncoded in ASCII as character hex 3E, decimal 62. The earliest known use of the symbols is found in Artis Analyticae Praxis ad Aequationes Algebraicas Resolvendas ( The Analytical Arts Applied to Solving Algebraic Equations) by Thomas Harriot, published posthumously in 1631. Since the development of computer programming languages, the greater-than sign and the less-than sign have been repurposed for a range of uses and operations. The less-than sign and greater-than sign always "point" to the smaller number. Examples of typical usage include 1.5 > 1 and 1 > −2. In mathematical writing, the greater-than sign is typically placed between two values being compared and signifies that the first number is greater than the second number. The widely adopted form of two equal-length strokes connecting in an acute angle at the right, >, has been found in documents dated as far back as 1631. The greater-than sign is a mathematical symbol that denotes an inequality between two values. That way you can validate whether a given answer is correct or not.U+2A7E ⩾ GREATER-THAN OR SLANTED EQUAL TO You may want to test equivalency when grading a test, for example. There are many cases where you may use comparison operators like the = operator. There is no need to convert data types to test equivalency. The table below summarizes the comparison operators available in JavaScript.īecause this operator is not strict about data type, it can support users entering strings instead of numbers, for example. Often, these operators are used with stored values in variables.Ĭomparison operators all return a Boolean (logical) value of true or false. In JavaScript, there are a number of comparison operators that you can use to evaluate whether given values are different or equal, as well as if a value is greater than or less than another. If you are interested in learning more about conditional statements first, refer to How To Write Conditional Statements in JavaScript. These are commonly used with conditional statements, and the if, else, and else if keywords, as well as the ternary operator. In this tutorial, we’ll go over logical operators. The JavaScript programming language uses operators to evaluate statements that can aid in control flow within programming. If you have a familiarity with logic, you know that it involves truth tables, Boolean algebra, and comparisons to determine equality or difference. The field of computer science has many foundations in mathematical logic.
