Important

Self-managed SingleStore will soon transition from version 9.1 RC to version 10. This new semantic versioning scheme will provide SingleStore with finer control over engine and feature releases that were not possible with the current versioning scheme.

In the interim, SingleStore 9.1 RC can be used to preview, evaluate, and provide feedback on the new and upcoming features in SingleStore 10 prior to its general availability. Ahead of this transition, SingleStore 9.0 is recommended for production workloads, which can later be upgraded to SingleStore 10.

TRUNC

On this page

The TRUNC() function returns the number x truncated to d decimal places. This is similar to the TRUNCATE function except that the precision (d) is not required.

If the precision is not specified, the number is truncated to 0 decimal places.

Note

If you do not specify a format, and if your value is not numeric, it will be treated like a date.

Syntax

SQL

TRUNC(x [,d])

Arguments

x: the number to be truncated
d: the number of decimal places

Return Type

Float or double.

Examples

SQL

SELECT TRUNC(PI());

|           3 |

SQL

SELECT TRUNC(42.422, 1);

+------------------+
| TRUNC(42.422, 1) |
