Arithmetic & Type Coercion

Luma supports all standard arithmetic operators, offering expressive syntax with smart, developer-friendly type handling.

Supported Operators

Operator	Description	Example	Result
+	Addition	a + b	Sum
-	Subtraction	a - b	Diff
*	Multiplication	a * b	Product
/	Division	a / b	Quotient
%	Modulo (remainder of division)	a % b	Remainder
-	Unary minus (negation)	-a	Negated value
++	Increment (adds 1 to integer)	a++	a + 1
--	Decrement (subtracts 1 from integer)	a–	a - 1

Automatic Type Coercion

One of Luma’s most developer-friendly features is implicit numeric type coercion. This means:

• Luma figures out type conversions for you based on the target variable type.
• You don’t need to manually cast (int(), float()) when using mixed types like int and float.
