Javascript function in transformation

Hello, is that possible to use zour own custom transformation function for data?

the point is the data is in Uint32 must be transformed to Float32.

The possible function is:
var BinaryToFloat = function (rawValue){
const buffer = new ArrayBuffer(16);
const view = new DataView(buffer);
view.setUint32(1,rawValue);
return view.getFloat32(1);
};

so that
BinaryToFloat(1120403456) equals to ‘100.0’

Any chances to implement such a transformation?
