The equal sign or equality sign (=) is a mathematical symbol used to indicate an equality, invented by Robert Recorde in 1557. In equations, the equal sign is placed between two (or more) expressions that have the same value. In Unicode and ASCII, U + 003D = EQUALS SIGN (HTML =).

In mathematics, the equal sign is as a statement of simple facts in certain cases (x = 2), or creates a definition (make x = 2), a conditional statement (if x = 2…), or universal. Represents the logical equivalence (x + 1) 2 = x2 + 2x + 1.

The first significant computer programming language that used the equal sign was Fortran’s original version, FORTRAN I, designed in 1954 and implemented in 1957. In Fortran, “=” acts as an assignment operator. X = 2 gives the value of X 2. This is a bit like using “=” in a mathematical definition but with different semantics. The expression following the “=” may be evaluated first and refer to the previous value of X. For example, increase the value of the allocation X = X + 2 X by 2.

The usage of rival programming languages ​​was pioneered by the original version of ALGOL, designed in 1958 and implemented in 1960. “As a conditional usage of mathematics. The equal sign was reserved for this usage.
