Give some examples of Volatile function.
Some of Excel’s functions are obviously volatile: RAND(), NOW(), TODAY()
Others are less obviously volatile: OFFSET(), CELL(), INDIRECT(), INFO()
Some are volatile in some versions of Excel but not in others: INDEX()became non-volatile in Excel 97.
A number of functions that are documented by Microsoft as volatile do not actually seem to be volatile when tested:
INDEX(), ROWS(), COLUMNS(), AREAS()
and CELL(“Filename”) IS volatile although a MSKBN article says its not.
One particular syntax of SUMIF is volatile in Excel 2002 and subsequent versions:
=SUMIF(A1:A4,”>0″,B1) is volatile whereas =SUMIF(A1:A4,”>0″,B1:B4) is not volatile.
