The Gawk manual explains this in its Basic Programming Concepts section. See:
http://www.gnu.org/manual/gawk/html_node/Floating-Point-Issues.html#Floating%20Point%20Issues
That web page mentions Goldberg's paper, whose URL has moved since the
www.gnu.org manual was last updated. Here's the current URL:
