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.
