It depends on the use case, but do you consider NaN to be equal to NaN? For an assert macro, I would expect so. Also, your code works differently for very large

It depends on the use case, but do you consider NaN to be equal to NaN? For an assert macro, I would expect so. Also, your code works differently for very large and very small numbers, eg. 1.0000001, 1.0000002 vs 1e-100, 1.0000002e-100. For my own soft-floating point math library, I expect the value is off by a some percentage, not just off by epsilon. And so I have my own almostSame method [1] which accounts for that and is quite a bit more complex. Actually multiple such methods. But well, that's just my own use case.
