MySQL's PI() method returns the value of π (pi). The default precision is 7 decimal places, however, the double-precision value is stored internally for calculations.

Parameters

No parameters.

Return value

The value of π.

Examples

To return the value of π:

SELECT PI();
+----------+
| PI() |
+----------+
| 3.141593 |
+----------+

Double-precision value is stored internally for calculations:

SELECT 0.000000000000 + PI();
+-----------------------+
| 0.000000000000 + PI() |
+-----------------------+
| 3.141592653590 |
+-----------------------+

As we added π with a number with a precision of 12, the returned value also has precision 12.
