Hi Amal,
the "Warp (Reproject)" processing algorithm allows you to set the output 
data type specifying it in the "Output data type" advanced parameter. 
Have you properly set it with the desired output data type?
Please refer to the algorithm help page already linked to find info 
about all the algorithm parameters.

In your initial message in this thread, you wrote that the "Translate 
(Convert Format)" processing algorithm converts the raster layers 
accurately except for the output resolution which you didn't know how to 
set, thus I suppose that with such algorithm the output data type is 
correct.
Have you set it or not in such algorithm? Have you tried to continue to 
use such algorithm and just add the -tr and -r additional parameters in 
the "Additional command-line parameters" algorithm parameter?

Best regards.

Andrea
