IEEE Standard 754 support
IEEE Standard 754 defines the representation and behavior of 32- and 64-bit floating point numbers. IEEE 754 support provides for consistency of basic computational results among platforms that use IEEE 754. A heavy-duty online discussion of floating point numbers and the standard is provided by David Goldberg at
