[PATCH] xrandr:an additional decimal for frequencies

I have an Samsung eh5000 HDTV that I connect to my Intel Mobile Ivy
Bridge chipset via HDMI1 as reported by xrandr. Without modification
xrandr reports the display's native resolution as
1920x1080 60.0 + 59.9 30.0 24.0 30.0 24.0*
This is confusing because it lists 30.0 and 24.0 twice each. I
discovered that I could switch to either one by specifying --rate
30/--rate 29.97 or --rate 24/--rate 23.98.
With the attached patch, I have added one more decimal everywhere a
frequency is reported so that now it's clearer what the supported
refresh rates are and how to switch to them:
1920x1080 60.00 + 59.94 30.00 24.00 29.97 23.98*
