This will simplify parsing of rational and (eventually) floating point numbers. Also streamlined inner loop. As a result, scan runs faster for all but short (<= 10 digit) numbers. For short numbers it is < 10% slower (cause is known and could be addressed in a future CL). Minor unrelated cleanups. Added additional tests. benchmark old ns/op new ns/op delta BenchmarkScanPi 134465 125122 -6.95% BenchmarkScan10Base2 493 540 +9.53% BenchmarkScan100Base2 3608 3244 -10.09% BenchmarkScan1000Base2 35376 32377 -8.48% BenchmarkScan10000Base2 481504 450028 -6.54% BenchmarkScan100000Base2 17936774 17648080 -1.61% BenchmarkScan10Base8 258 280 +8.53% BenchmarkScan100Base8 1389 1323 -4.75% BenchmarkScan1000Base8 14221 13036 -8.33% BenchmarkScan10000Base8 271298 258993 -4.54% BenchmarkScan100000Base8 15715465 15672580 -0.27% BenchmarkScan10Base10 249 268 +7.63% BenchmarkScan100Base10 1324 1220 -7.85% BenchmarkScan1000Base10 13398 12234 -8.69% BenchmarkScan10000Base10 259157 249342 -3.79% BenchmarkScan100000Base10 15670613 15582409 -0.56% BenchmarkScan10Base16 231 251 +8.66% BenchmarkScan100Base16 1093 1065 -2.56% BenchmarkScan1000Base16 12687 12196 -3.87% BenchmarkScan10000Base16 282349 271443 -3.86% BenchmarkScan100000Base16 16742669 16552917 -1.13% Change-Id: I4b9b078792788aef872b307399f00ffd34903127 Reviewed-on: https://go-review.googlesource.com/2960 Reviewed-by: Alan Donovan <adonovan@google.com> |

The Go Programming Language
Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.

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
Please note that we do not use pull requests.

Binary Distribution Notes
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.
