This was converted to 1.24 ×10¹² decimal digits. Kanada estimates the method is about twice the speed of the AGM methods he was previously using - and has other advantages to make such a huge computation feasible.

• David Bailey provides more detail on the background of the calculation (in PDF).
• Full details and statistics are promised soon.
