High Quality Content by WIKIPEDIA articles! IBM System/360 computers, and subsequent machines based on that architecture (mainframes), support a binary floating-point format. A hexadecimal dump of the format is used by SAS Transport files as required by the Food and Drug Administration (FDA) for New Drug Application (NDA) study submissions. See TS-140 . It is also used in GRIB data files to exchange the output of weather prediction models, in GDSII stream format files, and in SEG_Y format files. In comparison to IEEE 754 floating-point, the IBM floating point format has a longer significand, and a shorter exponent.
