<!-- ==================== CLASS DESCRIPTION ==================== -->
<h1 class="epydoc">Class IS_FLOAT_IN_RANGE</h1><span class="codelink"><a href="web2py.gluon.validators-pysrc.html#IS_FLOAT_IN_RANGE">source code</a></span><br /><br />
<pre class="base-tree">
object --+

<strong class="uidshort">IS_FLOAT_IN_RANGE</strong>
</pre>
<hr />
<p>Determine that the argument is (or can be represented as) a float, and
that it falls within the specified inclusive range. The comparison is
made with native 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_FLOAT_IN_RANGE(0, 10))
>>> IS_FLOAT_IN_RANGE(1,5)('4')
(4.0, None)
>>> IS_FLOAT_IN_RANGE(1,5)(4)
(4.0, None)
>>> IS_FLOAT_IN_RANGE(1,5)(1)
(1.0, None)
>>> IS_FLOAT_IN_RANGE(1,5)(5.25)
(5.25, 'enter a number between 1 and 5')
>>> IS_FLOAT_IN_RANGE(1,5)(6.0)
(6.0, 'enter a number between 1 and 5')
>>> IS_FLOAT_IN_RANGE(1,5)(3.5)
(3.5, None)
>>> IS_FLOAT_IN_RANGE(1,None)(3.5)
(3.5, None)
>>> IS_FLOAT_IN_RANGE(None,5)(3.5)
(3.5, None)
>>> IS_FLOAT_IN_RANGE(1,None)(0.5)
(0.5, 'enter a number greater than or equal to 1')
>>> IS_FLOAT_IN_RANGE(None,5)(6.5)
(6.5, 'enter a number less than or equal to 5')
>>> IS_FLOAT_IN_RANGE()(6.5)
(6.5, None)
>>> IS_FLOAT_IN_RANGE()('abc')
('abc', 'enter a number')
