Description
Precaution for Handling the Data Types

Both immediate values and variables can use the values within the ranges
defined for each type.
• Integer immediate value: − 2147483648 to 2147483647
• Decimal immediate value: − 2147483648. to 2147483647.
• Bit type: 0, 1
• Word type: − 32768 to 32767
• Long word type: − 2147483648 to 2147483647
• Real number type: ± (1.175E-38 to 3.402E+38), 0
• Indirect specification type: 0 to 10239
• The value in the second term is assigned to the first term.
• If the types are different on both sides, the type on the right is converted
to that of the left.
• If the value on the right side cannot be stored in the left side, the alarm
[2005h: Operation overflow] will occur.
1. Bit type
• When the bit type is used, all the operands must be the bit type.
• The integer immediate values 0 and 1 are treated as the bit type.
2. Types other than the bit type
• Types other than the bit type are prioritized in the following order
Real number type > Long word type > Word type
• Operation is performed in the type of the highest priority, and the op-
eration result will be stored after being converted to the type on the left.
• The integer immediate value is treated as long word type, and the dec-
imal immediate value is treated as real number type.
