This page is a reference to the various data types and formats that are used while scripting.
Int data type is a 32-bit signed two's complement integer
Minimum value is - 2,147,483,648 (-2^31)
Maximum value is 2,147,483,647(inclusive) (2^31 -1)
Integer is generally used as the default data type for integral values unless there is a concern about memory
The default value is 0
Example: int a = 100000, int b = -200000
- Long data type is a 64-bit signed two's complement integer
- Minimum value is -9,223,372,036,854,775,808(-2^63)
- Maximum value is 9,223,372,036,854,775,807 (inclusive)(2^63 -1)
- This type is used when a wider range than int is needed
- Default value is 0L
- Example: long a = 100000L, long b = -200000L
Float data type is a single-precision 32-bit IEEE 754 floating point
Float is mainly used to save memory in large arrays of floating point numbers
Default value is 0.0f
Float data type is never used for precise values such as currency
Example: float f1 = 234.5f
double data type is a double-precision 64-bit IEEE 754 floating point
This data type is generally used as the default data type for decimal values, generally the default choice
Double data type should never be used for precise values such as currency
Default value is 0.0d
Example: double d1 = 123.4
- boolean data type represents one bit of information
- There are only two possible values: true and false
- This data type is used for simple flags that track true/false conditions
- Default value is false
- Example: boolean one = true
String types of literals can contain any Unicode characters
- Example: String a = "\u0001"
See the Ignition documentation for various date functions: DateTime
The list can be written as comma-separated values (items) between square brackets.
- Items in a list need not be of the same type.
- List indices start at 0, and lists can be sliced, concatenated and so on.
list l1 = ['Sarah', 'process segment', 100, 2018]
list l2 = [1, 2, 3, 4, 5 ]
list l3 = ["a", "b", "c", "d"]
