3.3 EXPRESSION AND OPERATORS
An expression may be a string or numeric constant, or a variable, or it may be a
combination of constants and variables with operators to produce a single value.
Operators perform mathematical or logical operations. The operators provided by the
CipherLab BASIC Compiler may be divided into four categories, namely, Assignment
Operator, Arithmetic Operators, Relational Operators, and Logical Operators.
3.3.1 ASSIGNMENT OPERATOR
The CipherLab BASIC Compiler supports an assignment operator: “=”. For example,
 Length% = 100
 PI! = 3.14159
 Company$ = “CipherLab Co., Ltd.”
3.3.2 ARITHMETIC OPERATOR
The arithmetic operators are:
Operator
Operation
Sample Expression
^
Exponentiation
A% = 9^3
-
Negation (unary)
A% = -B%
*
Multiplication
A! = B! * C!
\
Division (integer)
A% = B! \ C!
/
Division (real)
A! = B! / C!
+
Addition
A% = B% + C%
-
Subtraction
A% = B% - C%
MOD
Modulo arithmetic
A% = B% MOD C%
