How can I awk just number.number from this output?

[linuxMaestro]

rlog passwd | grep revision | awk {'print $2'}
gives me:
revisions:
1.9
1.8
1.7
1.6
1.5
1.4
1.3
1.2
1.1
revision

I want it to only show the numbers, not revisions: or revision

 

[PHV]

rlog passwd | awk '/revision/{if($2!~"revision")print $2}'

Hope This Helps, PH.
