So every 2 bytes will contain approximately 4.5154 decimal digits. Ignoring memory usage and overhead, the number of digits in the largest possible long integer that can fit in 400 megabytes is
>>> import math >>> 200 * 1024 * 1024 * 15 * math.log10(2) 946958486.2000643 Since memory space is required for temporary storage of intermediate results, you won't actually be able to create a number that large if you only have 400 megabytes. casevh -- http://mail.python.org/mailman/listinfo/python-list
