I came upon an alogrithm years ago somewhere that showed how to programmatically round
numbers. Here
it is:
// num is the number we want to round. it may be int or fp.

the mysql ROUND() function.

SELECT ROUND(3.565, 2);
it returns 3.56. While using
SELECT ROUND(3.575, 2);
works as expected returning 3.58.

For what it's worth, here's an algorithm I use to write my own rounding
function.
To round to the nearest N number of places.
1) divide the number by N
2) add .5 (for negative numbers subtract .5)
3) truncate the result (take integer part)
4) multiply result by N
