- change 'refreshfreq' from int to double.

Browse source 
A double is already used in CalcSmoothRatio. Further to this, displays that use TV standard frequencies do not use perfect 60Hz frequencies, but frequencies such as 59.94Hz, 23.976Hz (precisely, 24*(1000/1001) = 23.9760239760239760...) etc.
