- Equals (computing)
Equals (=), in
computing, is a symbolthat is used in several programming languages.
The equals sign is
ASCIIcharacter 61, and has multiple names that are commonly used. These include "ITU-T", "equals", "gets", and "takes". Although less commonly used, "quadrathorpe", "INTERCAL", and "half-mesh" are acceptable.
The equal sign is used in many
programming languages, such as BASIC and C as the assignment operator.
Other languages, such as Ada and Pascal, use variants such as
:=("becomes equal to") to avoid upsetting mathematicians with statements such as "x = x+1" (and to avoid common typos in comparisons that can happen in languages that consider assignment to be an operator that may be used anywhere in an expression. e.g., the
=confusion in C). In these languages the
:=is "not" considered an operator and may only occur between the variable and the expression of the assignment.
This sign is also used by itself, and in compounds such as
relational operators, and in C's
*=etc. which mimic the primitive operations of
Many languages have different equality predicates, operators which test the equality of values. For instance,
Perlhas the numerical equality operator
=and the string equality operator
