Common Keys

The common keys section under Operators and Functions lists the operators and symbols most frequently used in mathematical expressions.

Button	Syntax	Definition
	DUMMY	Inserts the constant DUMMY at the cursor. This constant is translated to the appropriate data type by the math engine.
	/	Division
	*	Multiplication
	-	Subtraction
	+	Addition
	(	Open Parenthesis
	%	Calculates the modulus (remainder) of a division operation. Examples: 11%3 = 2 (11÷3 = 3 remainder 2) 12%4 = 0 (12÷4 = 3 remainder 0)
	sqrt(x)	Calculates the square root of x.
	**	Exponent: Raises a value to the power of another. For example: 2 ** 3 = 8 (2 to the power of 3)
	)	Closed Parenthesis
	e	Calculates the natural logarithm of x (base e).
		The constant value of π is approximately 3.14159265358979.
	=	Equality: Tests if two values are equal in expressions or assigns values in declarations.
	@Var#	Temporary Variables Names. Represents temporary variable names used during runtime and are not saved in the database.

Dummy (or placeholder) values are treated differently by some operators than by others.

Logical operators (!,>, <, >=, <=, ==, !=, &&, ||) treat DUMMY values as if they were regular numbers or the boolean TRUE. These operators do not check whether the value is a placeholder.
Mathematical operators (+, -, *, /, **, % etc.) check for DUMMY values. If any operand is a DUMMY, the result will always be a DUMMY.
