Try sage: R = RealField(500) sage: h = R(10)^-20 sage: print (R(2.7)^h-1)/h 0.9932517730102833901726770015061532639415526726048180749159032931769966 089695123374514625906903549365273146831326783123824292605435199290675977 83729094 - Robert --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
