Dit tal er A .........eks.337
Dit resultat B ..........i dette eksempel = 440

Hvis ikke du kan følge formlen, så er forklaringen her :
Du laver en division med 10 ( fordi du vil oprunde til nærmeste 10) hvor du fjerner alt efter kommaet ( INT
).......derefter ganger du igen med 10. Til sidst lægger du 10 til for at runde op til nærmeste 10..........håber du
forstod det ?

A = 337
B = (Int(A / 10) * 10) + 10

Here is a bug. Lets say that A is 340 then B becomes 350, that's not what he
wonted. This however is more correct.

If Int(A / 10) = (A / 10) Then
B = A
Else
B = (Int(A / 10) * 10) + 10
End if

The lines above fixes a bug in Steen's code.

Assuming that you are working with integers (longs) and that you
always want to round up to the nearest number dividable by 10, you
should use this formula:

RoundedNumber = ((Number + 9) \ 10) * 10
