+==================
+The Currency Field
+==================
+
+The currency field is a numerical field, specifically designed to manage
+monetary values.
+
+ >>> from z3c.currency import field, interfaces
+
+ >>> price = field.Currency(
+ ... title=u'Price',
+ ... description=u'The price of the item.')
+
+Besides the common attributes, the currency field also provides two additional
+attributes, the precision and unit. The precision is intended to allow for
+specifying whether the value is provided whole units or 1/100th of the whole
+unit -- in the US dollar and cents. By default this field is set to cents:
+
+ >>> price.precision is interfaces.CENTS
+ True
+
+It can be set to be dollars
+
+ >>> price.precision = interfaces.DOLLARS
+ >>> price.precision is interfaces.DOLLARS
+ True
+
+Note: Is there a more "internationalized" word for the whole unit of a
+currency?
+
+The unit specifies the symbol of the currency used. It is also used for
+formatting the numerical value to a string.
+
+ >>> price.unit
+ u'$'
+ >>> price.unit = u'€'
+ >>> price.unit
+ u'\xe2\x82\xac'
+
+Of course, both of those attributes are available as constructor arguments:
+
+ >>> price = field.Currency(
+ ... title=u'Price',
+ ... description=u'The price of the item.',
+ ... precision=interfaces.DOLLARS,
+ ... unit=u'€')
+
+ >>> price.precision is interfaces.DOLLARS
+ True
+ >>> price.unit
+ u'\xe2\x82\xac'
+
+Let's now have a look at the validation. First of all, the value must always
+be a decimal:
+
+ >>> import decimal
+ >>> price.validate(decimal.Decimal('12'))
+
+ >>> price.validate(12)
+ Traceback (most recent call last):
+ ...
+ ValidationError: Value must be of type 'Decimal', not 'int'.
+
+ >>> price.validate(12.0)
+ Traceback (most recent call last):
+ ...
+ ValidationError: Value must be of type 'Decimal', not 'float'.
+
+Also, when the precision is set to DOLLARS as it is the case here, the value
+must be a whole number:
+
+ >>> price.validate(decimal.Decimal('12'))
+
+ >>> price.validate(decimal.Decimal('12.01'))
+ Traceback (most recent call last):
+ ...
+ ValidationError: The value must be a whole number.
+
+ >>> price.validate(decimal.Decimal('12.00'))
+ Traceback (most recent call last):
+ ...
+ ValidationError: The value must be a whole number.
+
+When the precision is set to cents, ...
+
+ >>> price.precision = interfaces.CENTS
+
+... then values only with two decimal places are accepted:
+
+ >>> price.validate(decimal.Decimal('12.00'))
+
+ >>> price.validate(decimal.Decimal('12'))
+ Traceback (most recent call last):
+ ...
+ ValidationError: The value must have two decimal places.
+
+ >>> price.validate(decimal.Decimal('12.0'))
+ Traceback (most recent call last):
+ ...
+ ValidationError: The value must have two decimal places.
+
+Note that the ``IFromUnicode`` interface is purposefully not supported:
+
+ >>> price.fromUnicode
+ Traceback (most recent call last):
+ ...
+ AttributeError: 'Currency' object has no attribute 'fromUnicode'
+
+
+``z3c.form`` Support
+--------------------
+
+This package also provides support for integration with the ``z3c.form``
+package. In particular it implements a data converter from the ``Currency``
+field to any widget accepting a unicode string.
+
+ >>> from z3c.currency import converter
+ >>> conv = converter.CurrencyConverter(price, None)
+ >>> conv
+ <DataConverter from Currency to NoneType>
+
+The converter easily produces a string from any value:
+
+ >>> conv.toWidgetValue(decimal.Decimal(12))
+ u'12'
+ >>> conv.toWidgetValue(decimal.Decimal(1200))
+ u'1,200'
+ >>> conv.toWidgetValue(decimal.Decimal(-12))
+ u'-12'
+ >>> conv.toWidgetValue(decimal.Decimal('-12.0'))
+ u'-12.00'
+ >>> conv.toWidgetValue(decimal.Decimal('-12.00'))
+ u'-12.00'
+
+Note that always two decimal places are printed.
+
+Let's now parse a value. The parser is a little bit for flexible, not only
+accepting the output values, ...
+
+ >>> conv.toFieldValue(u'12')
+ Decimal("12")
+ >>> conv.toFieldValue(u'1,200')
+ Decimal("1200")
+ >>> conv.toFieldValue(u'-12')
+ Decimal("-12")
+ >>> conv.toFieldValue(u'-12.00')
+ Decimal("-12.00")
+
+but also other input values:
+
+ >>> conv.toFieldValue(u'1200')
+ Decimal("1200")
