# SetupData

## Description

Setup data types. This command allows you to select the data types used in the round-robin carousel in the Data (action `MakeData`) command.

Valid data types are:

| Data Type   | Size           |
| ----------- | -------------- |
| byte        |                |
| word        | 2 bytes        |
| double word | 4 bytes        |
| float       | 4 bytes        |
| quadro word | 8 bytes        |
| double      | 8 bytes        |
| long double | 10 or 12 bytes |
| packed real | 10 or 12 bytes |
| octa word   | 16 bytes       |

Naturally, not all data types are usable for all processors. For example, Intel 8051 processor doesn't have the 'double word' type. Furthermore, this command allows you to select a data type for the current undefined item and convert it to data. Please note that if the current processor does not support a data type, you cannot assign it even if you have selected it. If you unselect all data types, IDA will use the 'byte' type.
