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.
