WebIn MySQL, many floating point number types can have a range specified using 2 values, the "precision" and the "scale" E.g. 'float (precision,scale)' for the datatype. This syntax means a number may be bits long, but may only have bits after the decimal point. E.g. a 'float (5,2)' field may have the values -999.99 to 999.99.
