Need to format the summary data for perf numbers of current vs previous

[darrenge]

The decimal precision of the Current and Previous makes things a little too convoluted. Is there a way to change the precision of the decimal value to match more what the BDN output shows?

For example, I have a run that the BDN output shows: 158.0 ns, but the Summary shows 157.6849781195327 ns. I understand that is more accurate, but it makes it a bit more difficult to read especially when you have the +/- delta and the previous as well as the long +/- of the previous too.
