hmm, an interesting quote:
"
To quote from “The Elements of Programming Style” by Kernighan and Plauger:
/10.0 times 0.1 is hardly ever 1.0/.
"
so here's one example where 10.0 times 0.1 *is* 1.0:
perl -Mbignum -le 'print (10.0 * 0.1 == 1.0)'
# 1, for true
not an isolated idiosyncrazy, for that matter.
