Changes in version 0.21-0 [2023-10-10]

BUG FIXES

• ‘../tests/round-tst.R’: Better at detecting non-validlong-double; needed e.g., for BDR's valgrind instrumented R checks.

• R bugzilla URL updates.

Changes in version 0.20-0 [2021-01-04]

NEW FEATURES

• New vignette ‘rationalRound’, comparing CRAN packagegmp's based exact rational rounding with our package'salgorithms.

BUG FIXES

• adapt ‘tests/’ to failing (NaN) for some"r3.C"cases, when there are no long doubles (as on Mac M1).

Changes in version 0.12-2 [2020-07-04]

NEW FEATURES

• inroundX()'s help page example, consider numerical noisewhen checking for equality of different versions.

• The ‘Rounding’ vignette now givesR 4.0.0's state andmentions mathematicalexact rounding via rational arithmetic.

BUG FIXES

• Tweaked ‘tests/’ slightly so they work on anR configuredwith--no-long-double.

Changes in version 0.12-1 [2020-01-14]

NEW FEATURES

• Addedtrace option to"r3d.C", as it failed on32-bit (Windows and Fedora 30) platforms, givingInf 7 out of16 times forroundX(.Machine$double.xmax, -(295:310), "r3d.C").

Changes in version 0.12-0 [2020-01-13]

NEW FEATURES

• Added rounding version"r3d.C", version of"r3.C"which isnot using anylong double and should match thepureR version"r3" more closely.

Changes in version 0.11-0 [2020-01-12]

NEW FEATURES

• externalizedround_r3() and addedinfo option.

• provide simple wrapperroundAll() to apply allroundVersions.

• Obey CRAN requirements by adding info to ‘DESCRIPTION’, etc.

• Added C rounding version"r3.C", by translating theRcode of"r3" to C, making use oflong double topossibly get extended accuracy.

Changes in version 0.10-1 [2020-01-06]

NEW FEATURES

• added"sprintf" version forround(); newroundVersions, Jan. 2.

• + first regression tests.

• AddedR (interface to libc) version of C99 libmath functionslogB(),ilogb(),nearbyint(),fpclassify(),isnormal(),signbit(), andnextafter().

• added"r2a.C" version ofround(), correspondingto my (svn r77618; Dec 24, 2019) commit to R-devel.

• added"r3", my “optimal”round() pureR version.

• newrandI() for random integers of specified number ofdigits, in order to create simulated data examples forround*() testing.

Changes in version 0.10-0 [2020-01-01]

NEW FEATURES

• New packageround:Implements several versions ofround(x, digits);with just the one functionroundX(x, digits, version) andpossible versionsc("r0", "r1", "r1a", "r2"), all via C codeof current (R-devel) and former (R and R-devel) versions ofR's ownround(x, digits).

  E.g.,"r2" is related to my change ofround() inR-devel via svn commit r77618, on 2019-12-24, with messagetweaks to round() bug fix for PR#17668 in r77609.
