Dinfio Documentation

Definition

Operator is the symbol used for changing, combining, and comparing values. Dinfio supports unary operators and binary operators. Unary operators are operators that operate on a single value, i.e. -a (minus), !a (not). And binary operators are operators that operate on two values, i.e. a + b (addition).

Dinfio divides operators into the following groups:

Arithmetic and string operators
Assignment and compound assignment operators
Comparison operators
Logical operators

Arithmetic and String Operators

Operator	Name	Example	Result
+	Addition	`5 + 2`	`7`
-	Subtraction	`5 - 2`	`3`
*	Multiplication	`5 * 2`	`10`
/	Division	`5 / 2`	`2.5`
\	Integer Division	`5 \ 2`	`2`
%	Modulus	`5 % 2`	`1`
^	Exponentiation	`5 ^ 2`	`25`
&	Concatenation	`"Hello " & "world"`	`"Hello world"`

Assignment and Compound Assignment Operators

Assignment	Equivalent To	Example	Result
`a = b`	No equivalent	`a = 1`	`a equals to 1`
`a += b`	`a = a + b`	`a = 1; a += 2`	`a is now equal to 3`
`a -= b`	`a = a - b`	`a = 3; a -= 2`	`a is now equal to 1`
`a *= b`	`a = a * b`	`a = 3; a *= 2`	`a is now equal to 6`
`a /= b`	`a = a / b`	`a = 3; a /= 2`	`a is now equal to 1.5`
`a \= b`	`a = a \ b`	`a = 3; a \= 2`	`a is now equal to 1`
`a %= b`	`a = a % b`	`a = 3; a %= 2`	`a is now equal to 1`
`a &= b`	`a = a & b`	`a = "Clara"; a &= "Aisha"`	`a is now equal to "ClaraAisha"`

Comparison Operators

Operator	Name	Example	Result
==	Equal to	`5 == 5`	`true`
!=	Not equal to	`5 != 5`	`false`
>	Greater than	`5 > 2`	`true`
<	Less than	`5 < 2`	`false`
>=	Greater than or equal to	`5 >= 2`	`true`
<=	Less than or equal to	`5 <= 5`	`true`

Logical Operators

Operator	Name	Example	Result
!	Logical NOT	`!true`	`false`
&&	Logical AND	`true && false`	`false`
\|\|	Logical OR	`true \|\| false`	`true`
^^	Logical XOR	`true ^^ false`	`true`
