A strict equality operator is also often available in those languages, returning true only for values with identical or equivalent types (in PHP, 4 === "4" is false although 4 == "4" is true). [ 3 ] [ 4 ] For languages where the number 0 may be interpreted as false , this operator may simplify things such as checking for zero (as x == 0 would ...
In logic, a set of symbols is commonly used to express logical representation. The following table lists many common symbols, together with their name, how they should be read out loud, and the related field of mathematics.
Other languages use different symbols for the two operators. [22] For example: In ALGOL and Pascal, the assignment operator is a colon and an equals sign (":=") while the equality operator is a single equals ("="). In C, the assignment operator is a single equals sign ("=") while the equality operator is a pair of equals signs ("==").
The semantics of operators particularly depends on value, evaluation strategy, and argument passing mode (such as Boolean short-circuiting). Simply, an expression involving an operator is evaluated in some way, and the resulting value may be just a value (an r-value), or may be an object allowing assignment (an l-value).

The two languages use different operators for assignment. Pascal, like ALGOL, uses the mathematical equality operator = for the equality test and the symbol := for assignment, whereas C, like B, uses the mathematical equality operator for assignment. In C (and B) the == symbol of FORTRAN was chosen for the equality test.
