10 | Release 2a (1998 December)\r | |
11 | \r | |
12 | -- Added functions to convert between 64-bit integers (int64) and all\r | |
13 | supported floating-point formats.\r | |
14 | \r | |
15 | -- Fixed a bug in all 64-bit-version square root functions except\r | |
16 | `float32_sqrt' that caused the result sometimes to be off by 1 unit in\r | |
17 | the last place (1 ulp) from what it should be. (Bug discovered by Paul\r | |
18 | Donahue.)\r | |
19 | \r | |
20 | -- Improved the makefiles.\r | |

23 | Release 2 (1997 June)\r | |
24 | \r | |
25 | -- Created the 64-bit (bits64) version, adding the floatx80 and float128\r | |
26 | formats.\r | |
27 | \r | |
28 | -- Changed the source directory structure, splitting the sources into a\r | |
29 | `bits32' and a `bits64' version. Renamed `environment.h' to `milieu.h'\r | |
30 | (to avoid confusion with environment variables).\r | |
31 | \r | |
32 | -- Fixed a small error that caused `float64_round_to_int' often to round the\r | |
33 | wrong way in nearest/even mode when the operand was between 2^20 and 2^21\r | |
34 | and halfway between two integers.\r | |

37 | Release 1a (1996 July)\r | |
38 | \r | |
39 | -- Corrected a mistake that caused borderline underflow cases not to raise\r | |
40 | the underflow flag when they should have. (Problem reported by Doug\r | |
41 | Priest.)\r | |
42 | \r | |
43 | -- Added the `float_detect_tininess' variable to control whether tininess is\r | |
44 | detected before or after rounding.\r | |
