':param min_value: Validation rule for the minimum acceptable value.
:param max_value: Validation rule for the maximum acceptable value.
:param force_string: Store as a string.
:param precision: Number of decimal places to store.
:param rounding: The rounding rule from the python decimal library:
- decimal.ROUND_CEILING (towards Infinity)
- decimal.ROUND_DOWN (towards zero)
- decimal.ROUND_FLOOR (towards -Infinity)
- decimal.ROUND_HALF_DOWN (to nearest with ties going towards zero)
- decimal.ROUND_HALF_EVEN (to nearest with ties going to nearest even integer)
- decimal.ROUND_HALF_UP (to nearest with ties going away from zero)
- decimal.ROUND_UP (away from zero)
- decimal.ROUND_05UP (away from zero if last digit after rounding towards zero would have been 0 or 5; otherwise towards zero)
Defaults to: ``decimal.ROUND_HALF_UP``'
