void

void is not really a data type, more like lack of data type. It can only be used to tell the compiler that a function doesn't return any data.

bool

bool is a boolean type with only two possible values: true or false. The keywords true and false are constants of type bool that can be used as such in expressions.

Integer numbers

type	min value	max value
`int8`	-128	127
`int16`	-32,768	32,767
`int`	-2,147,483,648	2,147,483,647
`int64`	-9,223,372,036,854,775,808	9,223,372,036,854,775,807
`uint8`	0	255
`uint16`	0	65,535
`uint`	0	4,294,967,295
`uint64`	0	18,446,744,073,709,551,615

As the scripting engine has been optimized for 32 bit datatypes, using the smaller variants is only recommended for accessing application specified variables. For local variables it is better to use the 32 bit variant.

int32 is an alias for int, and uint32 is an alias for uint.

Real numbers

type	range of values	smallest positive value	maximum digits
`float`	+/- 3.402823466e+38	1.175494351e-38	6
`double`	+/- 1.79769313486231e+308	2.22507385850720e-308	15

Note: These numbers assume the platform uses the IEEE 754 to represent floating point numbers in the CPU

Rounding errors may occur if more digits than the maximum number of digits are used.

Curiousity: Real numbers may also have the additional values of positive and negative 0 or infinite, and NaN (Not-a-Number). For float NaN is represented by the 32 bit data word 0x7fc00000.
