For the nearest lower, even number: =IF(ISEVEN(ROUNDUP(B6,0)),ROUNDDOWN(B6,0),ROUNDUP(B6,0))-1

Hi, bb, thanks for your respond. I have modified and updated the article according to your suggestion, now it lists formulas on rounding up or down to nearest odd or even number.

=IF(EVEN(B6)>B6,EVEN(B6)-2,EVEN(B6)) also works well.

Thanks for your supplement.

I came up with this.

=IF(ISODD(ROUNDUP(A4,0)),ROUNDDOWN(A4,0),ROUNDUP(A4,0))

=EVEN(A2) DOES NOT Round to the NEAREST(!) Even number. To the best of my knowledge it ROUNDS UP(!) to Nearest Even Number. Try it on: 34.0014 and 20.999. One of the possible formulas to return the Nearest Even number is: =INT(A2/2+0.5)*2

We use Excel for our Estimating templates and use the following formula to round: =ROUND(A2/2,0)*2 And for our formulas that our foremen receive, we use to folllowing (so they don't have our waste factors, because they'll use that extra 10% of material!): =ROUND(A2/2,-1)*2 Hope this helps!

I posted my solution above, if you are interested. Know this is kind of old.

Yep, as I said (quote): "One of the possible formulas to return the Nearest Even number is: =INT(A2/2+0.5)*2"
I, usually, try to use the shortest formula out of many possibilities.
