network script incorrectly parsing iperf output

A sample run of network script on a really fast link results in this:

[ 3] local 172.100.202.227 port 39630 connected with 172.100.202.223 port 5001
[ ID] Interval Transfer Bandwidth
[ 3] 0.0- 0.9 sec 1.00 GBytes 9.14 Gbits/sec
Transfer speed: 14 Gb/s
70.00% of theoretical max 20000Mb/s

Raw iperf output says 9.14 Gbits/sec, but the parsed result (the one with "Transfer Speed:" says 14 Gb/s. It's parsing the units correctly, but not the quantity, chopping off what's before the decimal point.
This is because the regex used to parse the speed won't consider a dot part of the quantity:

       match = re.search(r'\d+\s([GM])bits', iperf_return)

it should be something like this:

       match = re.search(r'[\d\.]+\s([GM])bits', iperf_return)
