MySQL's TRUNCATE(~) method returns the input number truncated to D decimal places.
NOTE
Truncation is not the same as rounding. Truncation will simply cut off anything after D decimal places without performing rounding.
Parameters
1. X | number
The number to truncate.
2. D | number
The number of decimal places to truncate to.
Return value
The input number truncated to D decimal places.
Examples
Basic usage
To truncate to 1 decimal place:
SELECT TRUNCATE(5.55, 1);
+-------------------+| TRUNCATE(5.55, 1) |+-------------------+| 5.5 |+-------------------+
Note that we simply get rid of the second decimal place rather than rounding to the nearest tenth to 5.6.
To truncate to zero decimal places:
SELECT TRUNCATE(567.52, 0);
+---------------------+| TRUNCATE(567.52, 0) |+---------------------+| 567 |+---------------------+
Negative decimal places
To truncate to hundreds:
SELECT TRUNCATE(567.52, -2);
+----------------------+| TRUNCATE(567.52, -2) |+----------------------+| 500 |+----------------------+
Note that everything starting two places left of the decimal point (i.e. tens column) is replaced with zero leaving only the hundreds column untouched.
