The +main class, BigFloat, gives an immutable multiple-precision floating-point +type that can be freely mixed with Python integers and floats. The Context +class, when used in conjunction with Pythons with statement, gives a simple +way of controlling precisions and rounding modes. Additional module-level +functions provide various standard mathematical operations. There is full +support for IEEE 754 signed zeros, nans, infinities and subnormals. diff --git a/libraries/python-bigfloat/doinst.sh b/libraries/python-bigfloat/doinst.sh new file mode 100644 index 0000000000..c9ae7e166c --- /dev/null +++ b/libraries/python-bigfloat/doinst.sh @@ -0,0 +1,3 @@ +#!/bin/bash + +python -m bigfloat.test.test_bigfloat diff --git a/libraries/python-bigfloat/python-bigfloat.SlackBuild b/libraries/python-bigfloat/python-bigfloat.SlackBuild new file mode 100644 index 0000000000..d509011a3e --- /dev/null +++ b/libraries/python-bigfloat/python-bigfloat.SlackBuild @@ -0,0 +1,73 @@ +#!/bin/sh + +# Slackware build script for python-bigfloat + +# Written by John Tyree + +PRGNAM=python-bigfloat +VERSION=${VERSION:-0.2.1} +BUILD=${BUILD:-1} +TAG=${TAG:-_SBo} + +SRCNAM=$(echo $PRGNAM | cut -d- -f2) + +if [ -z "$ARCH" ]; then + case "$( uname -m )" in + i?86) ARCH=i486 ;; + arm*) ARCH=arm ;; + *) ARCH=$( uname -m ) ;; + esac +fi + +CWD=$(pwd) +TMP=${TMP:-/tmp/SBo} +PKG=$TMP/package-$PRGNAM +OUTPUT=${OUTPUT:-/tmp} + +if [ "$ARCH" = "i486" ]; then + SLKCFLAGS="-O2 -march=i486 -mtune=i686" + LIBDIRSUFFIX="" +elif [ "$ARCH" = "i686" ]; then + SLKCFLAGS="-O2 -march=i686 -mtune=i686" + LIBDIRSUFFIX="" +elif [ "$ARCH" = "x86_64" ]; then + SLKCFLAGS="-O2 -fPIC" + LIBDIRSUFFIX="64" +else + SLKCFLAGS="-O2" + LIBDIRSUFFIX="" +fi + +set -e + +rm -rf $PKG +mkdir -p $TMP $PKG $OUTPUT +cd $TMP +rm -rf $PRGNAM-$VERSION +tar xvf $CWD/$SRCNAM-$VERSION.tar.gz +mv $SRCNAM-$VERSION $PRGNAM-$VERSION +cd $PRGNAM-$VERSION +chown -R root:root . +find . \ + \( -perm 777 -o -perm 775 -o -perm 711 -o -perm 555 -o -perm 511 \) \ + -exec chmod 755 {} \; -o \ + \( -perm 666 -o -perm 664 -o -perm 600 -o -perm 444 -o -perm 440 -o -perm 400 \) \ + -exec chmod 644 {} \; + +python setup.py install --root=$PKG + +find $PKG -print0 | xargs -0 file | grep -e "executable" -e "shared object" | grep ELF \ + | cut -f 1 -d : | xargs strip --strip-unneeded 2> /dev/null || true + +mkdir -p $PKG/usr/doc/$PRGNAM-$VERSION +cp -a \ + README PKG-INFO CHANGELOG \ + $PKG/usr/doc/$PRGNAM-$VERSION +cat $CWD/$PRGNAM.SlackBuild > $PKG/usr/doc/$PRGNAM-$VERSION/$PRGNAM.SlackBuild + +mkdir -p $PKG/install +cat $CWD/slack-desc > $PKG/install/slack-desc +cat $CWD/doinst.sh > $PKG/install/doinst.sh + +cd $PKG +/sbin/makepkg -p -l y -c n $OUTPUT/$PRGNAM-$VERSION-$ARCH-$BUILD$TAG.${PKGTYPE:-tgz} diff --git a/libraries/python-bigfloat/python-bigfloat.info b/libraries/python-bigfloat/python-bigfloat.info new file mode 100644 index 0000000000..e7f5d53846 --- /dev/null +++ b/libraries/python-bigfloat/python-bigfloat.info @@ -0,0 +1,10 @@ +PRGNAM="python-bigfloat" +VERSION="0.2.1" +HOMEPAGE="http://bitbucket.org/dickinsm/bigfloat" +DOWNLOAD="http://pypi.python.org/packages/source/b/bigfloat/bigfloat-0.2.1.tar.gz" +MD5SUM="5260728c060ce511b6e23018b76fc2e0" +DOWNLOAD_x86_64="" +MD5SUM_x86_64="" +MAINTAINER="John Tyree" +EMAIL="johntyree+removethis@gmail.com" +APPROVED="Niels Horn" diff --git a/libraries/python-bigfloat/slack-desc b/libraries/python-bigfloat/slack-desc new file mode 100644 index 0000000000..fa8a0ca230 --- /dev/null +++ b/libraries/python-bigfloat/slack-desc @@ -0,0 +1,20 @@ +# HOW TO EDIT THIS FILE: +# The "handy ruler" below makes it easier to edit a package description.
