Description: Unable to select refresh rates with decimal place, Making some modes unselectable at all.
I do not want to use labels to select modes. I want to simply select refresh only ie xrandr -r xy.zz

The rate in xrandr appears to be a short. http://www.x.org/archive/X11R7.5/doc/man/man3/Xrandr.3.html
And docs says it picks nearest match.
This is not acceptable for the following situation:

With 3 refresh rates setup, The middle is NEVER able to be selected because it's a short int:
Nearest match to 60 IS 60
Nearest match to 61 IS 61

60
60.5
61

Additional info:
* xrandr 1.4 I believe

Note: Using xrand 1.2 mode fails to work or I don't understand it's usage.
eg.
xrandr --q12 -r 60.5
This task depends upon

Two different systems, But same (Imaged) Arch.

Intel and Radeon.

This is just how the RANDR interface was built. Rate is passed as short, so you can't pass anything which is not an integer. This is not the place to file a bug for this, as upstream decides the protocol.
