C# switch statement limitations - why?
...t the same
thing as a big if-else statement.
Each case must be unique and evaluated

...more do you want?
Go on, ask me what the largest integer is, such that it and all smaller integers can be stored in IEEE 64-bit doubles without losing precision. An IEEE 64-bit double has 52 bits of mantissa, so I think it's 253:
253 + 1 cannot be stored, because the 1 at the start and the 1 at t...
