Can someone answer my questions "What are the different methods of
representing numerical data"?

Sounds like a test question. What's the context? Is it asking about
numerical formats? Or is it asking about date v. time v. other numerical
data?

(Which really is not "different methods" per se. All are floating-point aka
real numbers. But the test might be asking for the specifics of date and
time representation.)
