./math/mpfr, GMP-based library for multiple-precision floating-point computations

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 4.2.1, Package name: mpfr-4.2.1, Maintainer: pkgsrc-users

The MPFR library is a C library for multiple-precision floating-point
computations with exact rounding (also called correct rounding). It is
based on the GMP multiple-precision library and should replace the MPF
class in further releases of GMP.

The main goal of MPFR is to provide a library for multiple-precision
floating-point computation which is both efficient and has a well-defined
semantics. It copies the good ideas from the ANSI/IEEE-754 standard for
double-precision floating-point arithmetic (53-bit mantissa).

Log message: devel/gmp, math/mpcomplex, math/mpfr: Tidy inplace.mk messaging. Use STEP_MSG and RUN to make this produce prettier output and play nicer with PKG_DEBUG &c. No functional change intended.

Log message: */builtin.mk: Use ${_CROSS_DESTDIR:U} for build-time file checks. These are questions about the target system, whose files at build-time are all relative to ${_CROSS_DESTDIR} if it is defined, i.e., if USE_CROSS_COMPILE is set to yes. No change to native builds because ${_CROSS_DESTDIR:U} is empty in them. (Possible minor change by adding :Q to ${H_FOO} in command lines, but if this makes a difference it likely fixes problems.)

Log message: mpfr: update to 4.2.1. Changes from version 4.2.0 to version 4.2.1: - Bug fixes (see <https://www.mpfr.org/mpfr-4.2.0/#fixed> and/or the ChangeLog file). - Improved MPFR manual. - Configure tests: replaced the test of the link with GMP, in order to avoid the use of a function without a prototype (Autoconf issue), as this is obsolescent in ISO C. The new test should be more robust.

Log message: mpfr: update to 4.2.0. Changes from versions 4.1.* to version 4.2.0: - The "fondue savoyarde" release. - Binary compatible with MPFR 4.0.* and 4.1.*, though some minor changes in the behavior of the formatted output functions may be visible, regarded as underspecified behavior or bug fixes (see below). - New functions mpfr_cosu, mpfr_sinu, mpfr_tanu, mpfr_acosu, mpfr_asinu, mpfr_atanu and mpfr_atan2u. - New functions mpfr_cospi, mpfr_sinpi, mpfr_tanpi, mpfr_acospi, mpfr_asinpi, mpfr_atanpi and mpfr_atan2pi. - New functions mpfr_log2p1, mpfr_log10p1, mpfr_exp2m1, mpfr_exp10m1 and mpfr_compound_si. - New functions mpfr_fmod_ui, mpfr_powr, mpfr_pown, mpfr_pow_uj, mpfr_pow_sj and mpfr_rootn_si (mpfr_pown is actually a macro defined as an alias for mpfr_pow_sj). - Bug fixes. In particular, for the formatted output functions (mpfr_printf, etc.), the case where the precision consists only of a period has been fixed to be like ".0" as specified in the ISO C standard, and the manual has been corrected and clarified. The macros of the custom interface have also been fixed: they now behave like functions (except a minor limitation for mpfr_custom_init_set).

See also: http://mail-index.netbsd.org/pkgsrc-users/2022/11/26/msg036540.html openscad has PKGREVISION++ because of icu update almost at the same time, and not packaged since then, so no PKGREVISION++ is necessary, (OK ?)
