I use the following to search for "M" at the end of a word :

=IF(EXACT(RIGHT(A1,1),"M"),1,0)

it returns 1 for true and 0 for false.

This is fine, but I need to expand the expression so that it returns 1 only
if the end of the string is a number followed by M.

For example :

xxxM = 0
3.2M =1
xxxm = 0
xxx m = 0
5M = 1
6.0M = 1

Can anyone help?

Thanks, Roger
