If I evaluate:
InputField[Dynamic[x], ImageSize -> {100, 20}, ContinuousAction ->
True]
Input 69.6 in the field. Now click outside of the field and then type
and evaluate x
In[179]:= x
Out[179]= 69.6
If you click in the output cell you'll see that x is in numerical
form, so I doubt you need to force InputField to display as Number.
(for underlying calculations, etc.) Although, I am a little confused
as to why your second example (using Number) would display all the
digits it does. If anything, shouldn't it be 69.600000000....? Seems
like a bug.
Maybe someone else will chime in.
