Assign numbers with decimals from a line to a variable

I am trying to assign a string of numbers with their decimals to a variable. The code reads a file called 'log'. I have not included the entire file since it's huge.

The line is:
 Tagging release with the label program-2.8.114...

My code:
BUILDNUMFORSIT=$(egrep 'Tagging release with the label program-' log | grep '[0-9]\{1,\}.[0-9]\{1,\}.[0-9]\{1,\}')

My output:
BUILDNUMFORSIT=' Tagging release with the label program-2.8.114...'

My desired output:

Please help!Smilie

one way: substitute the last
| grep '[0-9]\{1,\}.[0-9]\{1,\}.[0-9]\{1,\}'

| awk -F '-' '{while(sub("\.$","",$2)){} ; print $2 }'

awk -F"-" '/Tagging release with the label program/ { print substr($NF,1,7); } ' log_file
