                IS_FLOAT_IN_RANGE

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.

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

example:

       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')

### __init__(self, minimum=global_settings.applications_parent, maximum=global_settings.applications_parent, error_message=global_settings.applications_parent, dot=`'``.``'`)
(Constructor)

source code

x.__init__(...) initializes x; see x.__class__.__doc__ for signature

Overrides: object.__init__
  (inherited documentation)

### formatter(self, value)

source code

For some validators returns a formatted version (matching the validator) of value. Otherwise just returns the value.
