FWIW, Free42 1.4.71 running on my ancient Pocket PC (w/ Windows Mobile 5.0, do you remember it?), both in decimal (25-digit incarnation) and binary versions, passes the test without problem, with the last place correctly rounded. Great!

I'm still using my Pocket PC for various reasons with the benefit of having both binary and decimal versions of Free42, plus Emu42.
