Is it possible to specify the output data type when running a TIN interpolation in QGIS 3.0?

I don't see any options I can use to specify the data type, it is defaulting to float64. I need the layer in float32 in order to work effectively in the following raster calculation operation. I can change the data type using gdal.translate, but this requires a separate step, and increases the already significant calculation time (I'm working with rasters with about 900 million cells).

I believe there were options to specify data type as well as use the resolution (as well as extent, which is still an option) of existing layers in the 2.x versions, but I no longer have the 2.18 installed.
