Hauser 1998 December 16 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Release 2a (1998 December) -- Added functions to convert between 64-bit integers (int64) and all supported floating-point formats. -- Fixed a bug in all 64-bit-version square root functions except `float32_sqrt' that caused the result sometimes to be off by 1 unit in the last place (1 ulp) from what it should be. (Bug discovered by Paul Donahue.) -- Improved the makefiles. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Release 2 (1997 June) -- Created the 64-bit (bits64) version, adding the floatx80 and float128 formats. -- Changed the source directory structure, splitting the sources into a `bits32' and a `bits64' version. Renamed `environment.h' to `milieu.h' (to avoid confusion with environment variables). -- Fixed a small error that caused `float64_round_to_int' often to round the wrong way in nearest/even mode when the operand was between 2^20 and 2^21 and halfway between two integers. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Release 1a (1996 July) -- Corrected a mistake that caused borderline underflow cases not to raise the underflow flag when they should have. (Problem reported by Doug Priest.) -- Added the `float_detect_tininess' variable to control whether tininess is detected before or after rounding. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Release 1 (1996 July) -- Original release. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
