I thought that the use of the "Discrete" was because it was a computer dating service; isn't computer data discrete?

Yes, you can say that computer data (numbers) are descrete, because computers can only calculate with discrete numbers, cos it knows only 0 and 1, nothing in between, and normally comps can only calculate Integers, but no reals.

To display and calculate with reals computers need a trick. In the same way they combine powers of 2 (= 1, 2, 4, 8, 16, 32, ...) to get Integers, they combine powers of 2 with negative exponents ( = 1/2, 1/4, 1/8, 1/16, 1/32,...) to get the "mantissa" of a real.

But it is impossible for computers to get exact real values, like 1/3 for example.

They only get near this value but are never exact.
