| 671 | FloatField and DecimalField |

| 672 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~ |

| 673 | :class:`FloatField` type is sometimes mixed up with :class:`DecimalField` type. |

| 674 | Although they both represent real numbers, they have different representation |

| 675 | systems. Float uses `floating number representation system`_, and decimal |

| 676 | (sometimes called *numeric* or *fixed point number*) uses `fixed point number |

| 677 | representation system`_. For both field types there is corresponding type in |

| 678 | `databases numeric types`_ and `python numeric types`_. |
