<strong class="uidshort">IS_DECIMAL_IN_RANGE</strong>
</pre>
<hr />
<p>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.</p>
<p>The minimum and maximum limits can be None, meaning no lower or upper
limit, respectively.</p>
example:
<pre class="literalblock">
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')
