            IS_DECIMAL_IN_RANGE

Determine that the argument is (or can be represented as) a Python Decimal, and that it falls within the specified inclusive range. The comparison is made with Python Decimal arithmetic.

The minimum and maximum limits can be None, meaning no lower or upper limit, respectively.

example:

   INPUT(_type='text', _name='name', requires=IS_DECIMAL_IN_RANGE(0, 10))

   >>> IS_DECIMAL_IN_RANGE(1,5)('4')
   (Decimal('4'), None)
   >>> IS_DECIMAL_IN_RANGE(1,5)(4)
   (Decimal('4'), None)
   >>> IS_DECIMAL_IN_RANGE(1,5)(1)
   (Decimal('1'), None)
   >>> IS_DECIMAL_IN_RANGE(1,5)(5.25)
   (5.25, 'enter a number between 1 and 5')
   >>> IS_DECIMAL_IN_RANGE(5.25,6)(5.25)
   (Decimal('5.25'), None)
   >>> IS_DECIMAL_IN_RANGE(5.25,6)('5.25')
   (Decimal('5.25'), None)
   >>> IS_DECIMAL_IN_RANGE(1,5)(6.0)
   (6.0, 'enter a number between 1 and 5')
   >>> IS_DECIMAL_IN_RANGE(1,5)(3.5)
   (Decimal('3.5'), None)
   >>> IS_DECIMAL_IN_RANGE(1.5,5.5)(3.5)
   (Decimal('3.5'), None)
   >>> IS_DECIMAL_IN_RANGE(1.5,5.5)(6.5)
   (6.5, 'enter a number between 1.5 and 5.5')
   >>> IS_DECIMAL_IN_RANGE(1.5,None)(6.5)
   (Decimal('6.5'), None)
   >>> IS_DECIMAL_IN_RANGE(1.5,None)(0.5)
   (0.5, 'enter a number greater than or equal to 1.5')
   >>> IS_DECIMAL_IN_RANGE(None,5.5)(4.5)
   (Decimal('4.5'), None)
   >>> IS_DECIMAL_IN_RANGE(None,5.5)(6.5)
   (6.5, 'enter a number less than or equal to 5.5')
   >>> IS_DECIMAL_IN_RANGE()(6.5)
   (Decimal('6.5'), None)
   >>> IS_DECIMAL_IN_RANGE(0,99)(123.123)
   (123.123, 'enter a number between 0 and 99')
   >>> IS_DECIMAL_IN_RANGE(0,99)('123.123')
   ('123.123', 'enter a number between 0 and 99')
   >>> IS_DECIMAL_IN_RANGE(0,99)('12.34')
   (Decimal('12.34'), None)
   >>> IS_DECIMAL_IN_RANGE()('abc')
   ('abc', 'enter a number')
