math/big: faster string conversion routines Eliminated unnecessary string conversions throughout and removed (internal) capability for arbitrary character sets in conversion routines (functionality was not exported and not used internally). benchmark old ns/op new ns/op delta BenchmarkDecimalConversion-8 198283 187085 -5.65% BenchmarkStringPiParallel-8 46116 47822 +3.70% BenchmarkString10Base2-8 216 166 -23.15% BenchmarkString100Base2-8 886 762 -14.00% BenchmarkString1000Base2-8 7296 6625 -9.20% BenchmarkString10000Base2-8 72371 65563 -9.41% BenchmarkString100000Base2-8 725849 672766 -7.31% BenchmarkString10Base8-8 160 114 -28.75% BenchmarkString100Base8-8 398 309 -22.36% BenchmarkString1000Base8-8 2650 2244 -15.32% BenchmarkString10000Base8-8 24974 21745 -12.93% BenchmarkString100000Base8-8 245457 217489 -11.39% BenchmarkString10Base10-8 337 288 -14.54% BenchmarkString100Base10-8 1298 1046 -19.41% BenchmarkString1000Base10-8 6200 5752 -7.23% BenchmarkString10000Base10-8 24942 22589 -9.43% BenchmarkString100000Base10-8 8012921 7947152 -0.82% BenchmarkString10Base16-8 156 107 -31.41% BenchmarkString100Base16-8 344 255 -25.87% BenchmarkString1000Base16-8 2067 1705 -17.51% BenchmarkString10000Base16-8 19026 16112 -15.32% BenchmarkString100000Base16-8 184038 163457 -11.18% Change-Id: I68bd807529bd9b985f4b6ac2a87764bcc1a7d2f7 Reviewed-on: https://go-review.googlesource.com/14926 Reviewed-by: Alan Donovan <adonovan@google.com>
Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.
For documentation about how to install and use Go, visit https://golang.org/ or load doc/install-source.html in your web browser.
Our canonical Git repository is located at https://go.googlesource.com/go. There is a mirror of the repository at https://github.com/golang/go.
Please report issues here: https://golang.org/issue/new
Go is the work of hundreds of contributors. We appreciate your help!
To contribute, please read the contribution guidelines: https://golang.org/doc/contribute.html
Unless otherwise noted, the Go source files are distributed under the BSD-style license found in the LICENSE file.
If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:
export GOROOT=$HOME/go export PATH=$PATH:$GOROOT/bin
See https://golang.org/doc/install or doc/install.html for more details.
