In the 'make compile-always' benchmark where Emacs compiles all its own 
.el files, 85% of the floating-point objects that Emacs creates have the 
low-order three bits zero. Of course this percentage is 
benchmark-specific; still, for this benchmark most of Emacs's floating 
point numbers come from things like hash-table parameters and suchlike; 
that is, even though they may not be integers they are "round numbers" 
in the sense that you mention.
