* in addition, Integer type variables have 2 other kinds of settings: adding or subtracting 1 to current value (same as mathematical expression 'my_integer_variable +/- 1' but more convenient when incrementing/decrementing an index by step of 1)

:- % for modulo

:- % for modulo

:- ** for power

:- ^ for power

:- logical operators (&& for "and", || for "or") where the operands can be booleans or numbers (0 is false, any non-zero is true) and the boolean result is converted to number (there is no "not" operator but there is a not() function shown in the list of available functions)
