Hi, Dieter:

But then... I think I remember a 12C program where two 7-digit constants were used to generate a 10-digit number... #-)

Seems to me I notice some kind of sarcarsm in that last remark. If that's the case, it's lost on me, I don't get what 7-digit/10-digit are you talking about, you have to be more specific or provide a link.

?!? – 355/113 = 3,14159292... which agrees with pi in exactly 7 significant digits. Both truncated (3,141592) and rounded (3,141593). The 8th significant digit is 3 units off.

I also don't understand your "?!?", I said "almost". Rounded to 8 significant digits Pi is 3.1415927 while 355/113 is 3.1415929, so the 8th digit is just 2 ulps off (out of a possible 10) so my "almost" is more than justified.

Sorry to have ruffled your feathers.
