Validator class

This validator allows validating serialized (or deserialized) float parameter values.

Usage: Let validator = FloatValidator(), then * validator.validate(5.5) -> 5.5 * validator.validate(4.0) -> 4.0 * validator.validate(4) -> 4.0 * validator.validate('4') -> 4.0 * validator.validate(math.inf) -> math.inf * validator.validate('Infinity') -> math.inf * validator.validate('-Infinity') -> -math.nan * validator.validate('false') -> ValueError * validator.validate('true') -> ValueError * validator.validate('foo') -> ValueError * validator.validate('inf') -> ValueError * validator.validate('infinity') -> ValueError * validator.validate('nan') -> ValueError
