in reply to Why does perl math suck?

perl -le 'print 5056.45 + 10112.92 eq 15169.37 ? "as expected" : "perl math sucks!"'
works as expected. The reason is that Perl uses more digits in floating point calculations than it stringifies, so stringification rounds off to the expected number. (I didn't invent this trick.)
