round up or down

[lsmft]

Is there a way to program a cell to automatically round a number up or down if the number being rounded is a sum of other numbers? I'd like to be able to round this $1.22 either up or down in $0.25 cent increments.

Example:
=sum($0.15+$1.07)=$1.22

Assuming you are summing A1 & B1 try

=ROUND(SUM(A1:B1)*4,0)/4

Assuming you are summing A1 & B1 try

=ROUND(SUM(A1:B1)*4,0)/4

Thank you much,
Works just fine.
