5-2-1. Type of Data
There are three types of data: "integer type", "real type" and "logical type".
• Integer type
Data of integer type accurately express integer values and can be zero, a positive integer or a
negative integer.
• Real type

negative real number.
• Logical type
Data of logical type may be either true (1) or false (0).
5-2-2. Constants
There are two types of constant: "integer constant" and "real constant"
• Integer constant
Integer constants are constants of integer type. They are expressed by up to eight digits and
are interpreted as a decimal number.
• Real constant
Real constants are constants of real type. They are expressed by up to eight digits including a
decimal point and are interpreted as a decimal number.
