Hi Aditya ,
One possibility is to leave the value as it is , and change the cell formatting to display it in millions :
#,,.##
will display 19.09 ;
#,,.#
will display 19.1
If you really want the value itself to be changed to 19.1 , then use the formula :
=ROUND(number/10^6,1)
where number is 19087169 without the commas , since with those extra commas , Excel takes it as text.
