math/big: wrap Float.Cmp result in struct to prevent wrong use Float.Cmp used to return a value < 0, 0, or > 0 depending on how arguments x, y compared against each other. With the possibility of NaNs, the result was changed into an Accuracy (to include Undef). Consequently, Float.Cmp results could still be compared for (in-) equality with 0, but comparing if < 0 or > 0 would provide the wrong answer w/o any obvious notice by the compiler. This change wraps Float.Cmp results into a struct and accessors are used to access the desired result. This prevents incorrect use.

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.
