round R package News

Changes in version 0.21-0.2 [2024-01-10]

Misc

• 2nd try: R CMD build added the ‘*.R’ to inst/doc, ...

Changes in version 0.21-0.1 [2023-12-07]

Misc

• R CMD build now added the ‘*.R’ to inst/doc, circumventing knitr's hack with _R_CHECK_LICENCE_.

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

BUG FIXES

• ‘../tests/round-tst.R’: Better at detecting non-valid long-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 package gmp's based exact rational rounding with our package's algorithms.

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

• in roundX()'s help page example, consider numerical noise when checking for equality of different versions.

• The ‘Rounding’ vignette now gives R 4.0.0's state and mentions mathematical exact rounding via rational arithmetic.

BUG FIXES

• Tweaked ‘tests/’ slightly so they work on an R configured with --no-long-double.

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

NEW FEATURES

• Added trace option to "r3d.C", as it failed on 32-bit (Windows and Fedora 30) platforms, giving Inf 7 out of 16 times for roundX(.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 is not using any long double and should match the pure R version "r3" more closely.

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

NEW FEATURES

• externalized round_r3() and added info option.

• provide simple wrapper roundAll() to apply all roundVersions.

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

• Added C rounding version "r3.C", by translating the R code of "r3" to C, making use of long double to possibly get extended accuracy.

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

NEW FEATURES

• added "sprintf" version for round(); new roundVersions, Jan. 2.

• + first regression tests.

• Added R (interface to libc) version of C99 libmath functions logB(), ilogb(), nearbyint(), fpclassify(), isnormal(), signbit(), and nextafter().

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

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

• new randI() for random integers of specified number of digits, in order to create simulated data examples for round*() testing.

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

NEW FEATURES

• New package round: Implements several versions of round(x, digits); with just the one function roundX(x, digits, version) and possible versions c("r0", "r1", "r1a", "r2"), all via C code of current (R-devel) and former (R and R-devel) versions of R's own round(x, digits).

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