The detailed semantics of "the" ternary operator as well as its syntax differs significantly from language to language. A top level distinction from one language to another is whether the expressions permit side effects (as in most procedural languages) and whether the language provides short-circuit evaluation semantics, whereby only the selected expression is evaluated (most standard ...
The syntax of JavaScript is the set of rules that define a correctly structured JavaScript program. The examples below make use of the ... The ternary operator can ...
OCaml expressions provide ternary operations against records, arrays, and strings: a.[b]<-c would mean the string a where index b has value c. [6] The multiply–accumulate operation is another ternary operator. Another example of a ternary operator is between, as used in SQL.
In certain computer programming languages, the Elvis operator, often written ?:, is a binary operator that returns the evaluated first operand if that operand evaluates to a value likened to logically true (according to a language-dependent convention, in other words, a truthy value), and otherwise returns the evaluated second operand (in which case the first operand evaluated to a value ...
and | are bitwise operators that occur in many programming languages. The major difference is that bitwise operations operate on the individual bits of a binary numeral, whereas conditional operators operate on logical operations. Additionally, expressions before and after a bitwise operator are always evaluated.
"PIC S9999", for example, would require a signed variable of four decimal digits precision. If specified as a binary field, this would select a 16-bit signed type on most platforms. ^i Smalltalk automatically chooses an appropriate representation for integral numbers.
For details and examples see Case (SQL). ^ Arithmetic if was marked as obsolescent in Fortran 90. It was deleted as of the Fortran 2018 Standard. ^ Pattern matching was added in Ruby 3.0. [16] Some pattern matching constructs are still experimental. ^ Fortran 90 added the MERGE intrinsic. Fortran 2023 added the C-like ternary operator.
Conceptually, an operator can be overloaded in the same way that a function can – acting differently based on the type of input. Some languages provide operators that are inherently overloaded (aka ad hoc polymorphic). For example, in Java the + operator sums numbers or concatenates strings.
