BrunoAltinet has uploaded a patch.
Description:
Some time ago a behaviour for numbers got broken. It starts going in as text if it's not double, which doesn't make much sense.
Hence i corrected that part in the SetValue<T>
Also, i corrected a common nullreferenceexception when seting null as a value to a cell
instead of value.ToString() i've put Convert.ToString(value) .
Same method
Hope that helps and you approve of it.
Great job, thanks!
