Z S ) r a
A text field which displays and coerces data of the `decimal.Decimal` type.
:param places:
How many decimal places to quantize the value to for display on form.
If unset, use 2 decimal places.
If explicitely set to `None`, does not quantize value.
:param rounding:
How to round the value during quantize, for example
`decimal.ROUND_UP`. If unset, uses the rounding value from the
current thread's context.
:param use_locale:
If True, use locale-based number formatting. Locale-based number
formatting requires the 'babel' package.
:param number_format:
Optional number format for locale. If omitted, use the default decimal
format for the locale.
