- Equals (computing)
**Equals (=)**, incomputing , is asymbol that is used in severalprogramming language s.**Names**The equals sign is

ASCII character 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.**Programming**The equal sign is used in many

programming language s, such as BASIC and C as theassignment 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

`<=`

,`>=`

,`=`

,`/=`

,`!=`

for variousrelational operator s, and in C's`+=`

,`*=`

etc. which mimic the primitive operations oftwo-address code .**Operators**Many languages have different equality predicates, operators which test the equality of values. For instance,

Perl has the numerical equality operator`=`

and the string equality operator`eq`

.Equality is a property of values, not objects. An operator which asks if two variables refer to the same data object is an "identity" predicate, such as Python's

`is`

orCommon Lisp 's`EQ`
