5.11 Details on the variable type
● For REAL data types, only the number of places after the decimal point can be changed.
Changing the type is illegal and generates an error message in the easyscreen_log.txt. file.
Example:
Var1.typ = "IBW"
Var2.typ = "R3"
Numerical formats
Numbers can be represented in either binary, decimal, hexadecimal or exponential notation:
Binary
Decimal
Hexadecimal

Examples:
Note
When codes are generated with the "GC" function, only numerical values in decimal or
exponential notation are evaluated, but not those in binary or hexadecimal notation.
