As any non-naïve float user is aware, the proper form of float comparisons is not to use < or > or == or !=, but rather, instead of using < (to follow along with your example), one should use:
Decimal('1.1') - 2.2 < epsilon
Not at all. This is quite incorrect for most use cases. Fuzzy comparisons are sometimes useful for equality testing, but almost never for ordering. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco
