It is an alias of System.Single. Syntax: float variable_name = value; WebJun 3, 2014 · A float is less accurate than a double, so if a fraction is not representable exactly in binary then is converted to double, may mean it's a little bit smaller or bigger than it ought to be. Avoid conversions with loss of precision and consider rounding errors when making floating point comparisions.
