Operators

An operator is a symbol or keyword indicating an arithmetic or logical operation that acts on one or more expressions. You also can use an operator to assign a value to a variable.

operator +

result = expression1 + expression2

Sums two variables. If both expressions are strings, the operator concatenates their contents. If one expression is a string and another one is numeric, the numeric expression will be converted to the equivalent string and concatenation performed.

expression1	expression2	result
integer	integer	integer
floating	floating	floating
string	string	string
integer	floating	floating
integer	string	string
floating	integer	floating
floating	string	string
string	integer	string
string	floating	string

   

operator -

result = expression1 - expression2

Finds the difference between two numbers.

expression1	expression2	result
integer	integer	integer
floating	floating	floating
string	string	floating
integer	floating	floating
integer	string	floating
floating	integer	floating
floating	string	floating
string	integer	floating
string	floating	floating

operator *

result = expression1 * expression2

Multiplies two numbers.

expression1	expression2	result
integer	integer	integer
floating	floating	floating
string	string	floating
integer	floating	floating
integer	string	floating
floating	integer	floating
floating	string	floating
string	integer	floating
string	floating	floating

   

operator /

result = expression1 / expression2

Divides two numbers.

expression1	expression2	result
integer	integer	floating
floating	floating	floating
string	string	floating
integer	floating	floating
integer	string	floating
floating	integer	floating
floating	string	floating
string	integer	floating
string	floating	floating

   

operator ^

result = expression1 ^ expression2

Raises expression1 to the power of an expression2.
The type of result is always floating.

operator mod

result = expression1 mod expression2

Divides the value of one expression by the value of another, and returns the remainder.
The type of result is always integer.

operator or

result = expression1 or expression2

Performs a logical disjunction on two expressions.
The type of result is always integer.

operator and

result = expression1 and expression2

Performs a logical conjunction on two expressions.
The type of result is always integer.

operator not

result = not expression

Performs logical negation on an expression.
The type of result is always integer.
