# Type Casts

| Expression                      | Example                 | Description                                                                                               |
| ------------------------------- | ----------------------- | --------------------------------------------------------------------------------------------------------- |
| `CAST(expr AS type`)            | `CAST(1.25 AS FLOAT)`   | Converts an expression to another data type. For conversions to a TEXT type, use TRY\_CAST.               |
| `TRY_CAST(text_expr AS type`)   | `CAST('1.25' AS FLOAT)` | Converts a text to a non-text type, returning null if the conversion could not be successfully performed. |
| `ENCODE_TEXT(none_encoded_str`) | `ENCODE_TEXT(long_str)` | Converts a none-encoded text type to a dictionary-encoded text type.                                      |

The following table shows cast type conversion support.
