<P> Single - precision floating - point format is a computer number format that occupies 4 bytes (32 bits) in computer memory and represents a wide dynamic range of values by using a floating point . </P> <P> In IEEE 754 - 2008 the 32 - bit base - 2 format is officially referred to as binary32 . It was called single in IEEE 754 - 1985 . In older computers, different floating - point formats of 4 bytes were used, e.g., GW - BASIC's single - precision data type was the 32 - bit MBF floating - point format . </P> <P> One of the first programming languages to provide single - and double - precision floating - point data types was Fortran . Before the widespread adoption of IEEE 754 - 1985, the representation and properties of the double float data type depended on the computer manufacturer and computer model . </P>
