You could use a help sheet, I doubt you want to use round in all 16777216 cells
assume you have values in A1:H500 in Sheet1, insert a new sheet and select
A1:H500, with A1 as the active cell type =Sheet1A1
press ctrl + enter, now you can copy and paste special as values over the
old values in Sheet1 or paste as values in place and if you want you can
delete Sheet1 and rename the help sheet to Sheet1
