Operating Functions

Chapter 5

5–43

The BASIC Module contains a complete set of arithmetic and logical

operators. We divide the operators into two groups, dual operand (dyadic)

operators and single operand (unary) operators.

The general form of all dual operand instructions is:

(expr) OP (expr), where OP is one of the following operators.

+ Addition Operator

Example: PRINT 3+2

/ Division Operator

Example: PRINT 100/5

** Exponentiation Operator

The Exponentiation Operator raises the first expression to the power of

the second expression. The maximum power to which you raise a

number is 255.

Example: PRINT 2**3

* Multiplication Operator

Example: PRINT 3*3

– Subtraction Operator

Example: PRINT 9–6

.AND. Logical AND Operator

Example: PRINT 3.AND.2

.OR. Logical OR Operator

Example: PRINT 1.OR.4

.XOR. Logical EXCLUSIVE OR operator

Example: PRINT 7.XOR.6
