Detecting an emulator's number representation

[grsbanks]

You need to try and force a calculation to return a number that can be represented exactly only in decimal, not in binary. Try \(\frac{1}{10^n}\) for various positive integer values of n.

Conversely, there are values that can only be represented exactly in binary, not in decimal with a fixed number of digits available, such as \(\frac{1}{2^n}\).
