MATLAB: Matlab rounding to zero

incorrect roundinginteger classroundingrounding to zerozero

I have some arrays that are ADC values and I simply need to convert them into actual voltage. This is easily done by ADC*Gain however when I do this Matlab gives me zero every time. Below is the code and I am multiplying (.05/65536), the ADC values are int16 data type. My ADC values are like 6000-8000 and so I should be getting around .005 or on the order of mV for my voltage. Any help would be appreciated.
for i=1:10000
    A(i,:) = (ans.Channels(1,1).Acquisitions(i,:))*(.05/65536);
end

Like Sean said, convert all variables to some floating point format. You might do something like,
for i=1:10000
  A(i,:) = double((ans.Channels(1,1).Acquisitions(i,:)))*(.05/65536);
end
