Round to nearest even number

[vinerunner]

Hi all!

I have the following question:

From an equation I get a number which is not round number but it's between 0-inf.
Let's say 81.321.

I would like to round this number to an even number.

So somehow like this: 81.321 -> 81 -> 82

The point is to get the "nearest" EVEN number.

My idea was that I'll use the floor function to make the rounded number but how can I make a number from that which is even for 100% sure?

Thanks!

Roughly, divide by two and do the floor, then multiply by two to get the value you want.
