Follow-up to https://golang.org/cl/21755. This turned out to be a bit more than just a few nits as originally expected in that CL. 1) The actual mantissa may be shorter than required for the given precision (because of trailing 0's): no need to allocate space for it (and transmit 0's). This can save a lot of space when the precision is high: E.g., for prec == 1000, 16 words or 128 bytes are required at the most, but if the actual number is short, it may be much less (for the test cases present, it's significantly less). 2) The actual mantissa may be longer than the number of words required for the given precision: make sure to not overflow when encoding in bytes. 3) Add more documentation. 4) Add more tests.

The Go Programming Language
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.
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
Note that we do not accept pull requests and that we use the issue tracker for bug reports and proposals only. Please ask questions on https://forum.golangbridge.org or https://groups.google.com/forum/#!forum/golang-nuts.

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.
