Data Types

Polar Script supports the following data types:

Data type	Notes	Default
Double	For floating point numbers stored in 8 bytes. -1.79769313486231E308 to -4.94065645841247E-324 (negative number). 4.94065645841247E-324 to 1.79769313486231E308 (positive number) Can be indicated by appending a # or R to a number, like: 128#	0
Decimal	For floating point numbers representing real numbers (such as money) stored in 16 bytes. +/-1.0 x 10^-28 to +/-7.9228 x 10²⁸ Can be indicated by appending a @ or D to a number, like: 1D	0
Long	Integer stored in 4 bytes. -2,147,483,648 to 2,147,483,647 Can be indicated by appending a % or I to a number, like: 32%	0
LongLong	Integer stored in 8 bytes. -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 Can be indicated by appending a & or L to a number, like: 255L#	0
String	Unicode texts with virtually unlimited length.	""
Boolean	A boolean, either True or False.	False
Date	A Date/Time	#1899-12-30#
Object	Any object, but not basic types as listed above or arrays.	Nothing
Variant	Any type of variable, either objects, arrays or basic types.	Empty
Array	An n-dimensional array (n >= 1) with values. Arrays can be either typed or untyped (Array of Variants)	Variant(-1)

Next to the above real data types, there is a number of pseudo data types. These are specific empty/uninitialized values for specific situations:

Data type	Meaning	Detect
Empty	A variant variable is not yet initialised. Behaves as default value for each type when used as such.	IsEmpty(pVariable)
Missing	A Variant parameter is omitted and no default value was specified. Behaves as default value for each type when used as such.	IsMissing(pVariable)
Void	A ?-expression on a missing object was performed, as in: lValue = lMissingObject?.Value Behaves as default value for each type when used as such.	IsVoid(pVariable)
Nothing	An empty object. Is also the default for object variables. Please be aware that IsObject(Nothing) returns True.	IsNothing(pVariable)
NULL	A database-null value. When used in functions or calculations may return error 'Invalid use of NULL'. Treated as an empty string when used in a concatenation.	IsNull(pVariable) IsNotNull(pVariable)
