    2.6 cannot be represented exactly as a floating-point number, but NSDecimal can represent this value exactly (that’s why we need NSDecimals in the first place).

    According to IEEE 754 Calculator, 2.6 gets converted to 2.5999999046325684, which is less than 2.6, and therefore compares as NSOrderedDescending.
