Question

I am trying to figure out how to essentially create a “floor” call based on a specific decimal place as opposed to a whole value. Below is a table of actual values and the desired result:

=========|=========
3.125    |  3.12
4.187    |  4.18
1.212    |  1.21
5.999    |  5.99

Is this possible with mysql? using the round function to the 2nd decimal place returns “bad” data and rounding to the third does not reach the goal either.

Answer 1

Use the TRUNCATE function:

SELECT TRUNCATE(3.125, 2)

Output:

 3.12
