WebThe most notable difference is that the built-in integer data types can only represent whole numbers, while the fixed-point data types also contain information on the position of the binary point, or the scaling of the number. This scaling allows the fixed-point data types to represent both integers and non-integers. There are also slight ... WebSep 1, 2011 · The traditional view is that the floating-point number format is superior to the fixed-point number format when it comes to representing sound digitally. In fact, while it may be counter-intuitive, there is a case to be made that the use of floating-point numbers yields lesser resolution than the use of fixed-point notation.
