Multiply by 4, round to the nearest integer, divide by 4?

There is a general method for this:

• Multiply your number by 4.
• Round to the nearest integer.
• Divide by 4.

In SQL:

ROUND(column * 4) / 4

I don't know the exact function name, but basically you use floor(4*x)/4. floor might be called int, to_int, or something like that.
