Analytics Software

Hi All,
I have numbers like $1000000, $12000000, $13989098 on my report.

Now the requirment is I want to see these numbers to be rounded off to the nearest million..

for example:

1) $1000000 should be shown as $1.00M
2) $12000000 should be shown as $12.00M
3) $13989098 should be shown as $13.98M

Please suggest me a way to get the above thing working.

Thanks in Advance..
