Simple Data types

The following simple data types are supported in the Langstack applications. These are ordered in an ascending (smallest to largest) manner as per their data size:

Data Type	Used for	Example
Boolean	Representing Logical Values	TRUE, FALSE
Character	A Single letter or a sign	A or Z
Integer	Whole number ranging between -263 and 263-1. This means the minimum value can be -9,223,372,036,854,775,808 and the maximum value can be 9,223,372,036,854,775,807	7 or 12 or 999
Numerical	Number and decimal value ranging between 4.9e-324 to 1.8e+308	3.1415926
Timestamp	Timestamp is a date and time representation that is stored as a number in an Epoch form. This enables it to be used in calculation easily and yet displays its value in the form "YYYY-MM-DD hh:mm:ss"	1970-01-01 00:00:01' UTC to '2038-01-19 03:14:07' UTC
DateTime	Contains both date and time parts along with the time zone. DateTime can read string values in the defined formats. In case the string data has a missing value for day, the code returned will be ‘1’. For example, the date “2022-04” will be returned as “2022-04-01 00:00:00”. In case the string data has a missing value for any element in the time, the code returned will be ‘0’. For example, the date “2022-04-15” will be returned as “2022-04-15 00:00:00”.	YYYY-MM-DD hh:mm:ss e.g. 2022-04-01 00:00:00 YYYY-MM-DDThh:mm:ss e.g. 2022-04-01T00:00:00
String	Alphanumeric Characters	Hello world, 123
GUID	Global Identification of objects, programs, records, and so on.	4byte-2byte-2byte-2byte-6byte
