====== Variable Data Types ======

Most data in //Zeolite// is managed by dynamically-typed variables, represented by [[zeolite:types:ZVAR]] handles, and manipulated using the set of functions listed on the [[zeolite:functions|function reference page]]. 

The tables below present the list of valid variable types (including [[#classes]]) by their 'token' (defined in the ''Zeolite_defines.h''), the numeric value of that token, and by the string returned by the [[zeolite:functions:ztype_GetName|ztype_GetName]] function. 








===== Basic types =====

^ Name string ^ Token ^ VarID ^ Description ^
| [NULL] | VarID_INVALID |  0  | Used for invalid variable handles, or uninitialised variables. |
| "void" | VarID_void |  1  | A variable with no data (but has a name). |
| "variant" | VarID_variant |  2  | A variable whose value is another variable, the type of which is free to change. This data type is and should only be used for variable input extension functions. |
| "bool" | VarID_bool |  3  | Boolean value. Data is a C/C++ 'bool' type. |
| "char" | VarID_char |  4  | 8-bit signed integer and/or ASCII character. |
| "byte" | VarID_byte |  5  | 8-bit unsigned integer. |
| "ubyte" | VarID_ubyte |  5  | Same as 'byte'. |
| "sbyte" | VarID_sbyte |  104  | 8-bit signed integer. |
| "short" | VarID_short |  6  | 16-bit signed integer. |
| "ushort" | VarID_ushort |  105  | 16-bit unsigned integer. |
| "int" | VarID_int |  7  | 32-bit signed integer. |
| "uint" | VarID_uint |  106  | 32-bit unsigned integer. |
| "int64" | VarID_int64 |  8  | 64-bit integer. |
| "float" | VarID_float |  9  | 32-bit floating-point variable. |
| "double" | VarID_double |  10  | 64-bit floating-point variable. |
| "colour" | VarID_colour |  13  | 24-bit colour variable. Data is a [[zeolite:types:ColourPixel]] struct. |
| "vector3c" | VarID_vector3c |  101  | A three-component 8-bit signed integer vector. Data is a [[zeolite:types:vector3c]] struct.|
| "vector3i" | VarID_vector3i |  102  | A three-component 32-bit signed integer vector. Data is a [[zeolite:types:vector3i]] struct.|
| "vector3f" | VarID_vector3f |  14  | A three-component floating-point vector. Data is a [[zeolite:types:vector3f]] struct.|
| "vector3d" | VarID_vector3d |  103  | A three-component double-precision floating-point vector. Data is a [[zeolite:types:vector3d]] struct.|
| "vector4c" | VarID_vector4c |  107  | A four-component 8-bit signed integer vector. Data is a [[zeolite:types:vector4c]] struct.|
| "vector4i" | VarID_vector4i |  108  | A four-component 32-bit signed integer vector. Data is a [[zeolite:types:vector4i]] struct.|
| "vector4f" | VarID_vector4f |  109  | A four-component floating-point vector. Data is a [[zeolite:types:vector4f]] struct.|
| "vector4d" | VarID_vector4d |  110  | A four-component double-precision floating-point vector. Data is a [[zeolite:types:vector4d]] struct.|
| "matrix3f" | VarID_matrix3f |  111  | A 3x3-component single precision floating point matrix. Data is a [[zeolite:types:matrix3f]] struct.|
| "voidptr" | VarID_voidptr |  20  | Memory address (32 bit). Data is a C/C++ 'void*' type. |
| "varid" | VarID_varid |  23  | A 32-bit integer, containing one of the VarID values enumerated in this table. |
| "hvar" | VarID_hvar |  25  | A variable handle. Data is a [[zeolite:types:ZVAR]] handle to another variable. |
