The existing code was incorrect for numbers that after rounding would become the smallest denormal float32 (instead the result was 0). This caused all.bash to fail if Float32() were used in the compiler for constant arithmetic (there's currently a work-around - see also issue 10321. This change fixes the implementation of Float.Float32 and adds corresponding test cases. Float32 and Float64 diverge at this point. For ease of review, this change only fixes Float32. Float64 will be made to match in a subsequent change. Fixes #10321.

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.
