You can identify the data type of almost every memory address on the screenshot. You just need to read their names.
fMass, fBrakeBias, fTractionLoss, TransmissionData.fEngineInertia
etc. You can easily tell that they're all float, because of the "f" on their names. (and because things like speed, mass, inertia, etc are generally expressed as float values).
And, about all the other addresses... their memory type is clearly expressed on their names as well
[dword]nMonetaryValue
[byte]Front lights
[dword]Index/Identifier
etc.
