For numbers with a decimal separator, by default Python uses float and Pandas uses numpy float64. Internally float types use a base 2 representation which is convenient for binary computers. Python’s Decimal documentation shows example float inaccuracies. a = 1.1 + 2.2 print(a) # 3.3000000000000003 print(type(a)) #
