Here's one way: sage: R = RealField(200) sage: h = R(10^(-20)) sage: (R(2.7)^h-1)/h 0.99325177301028339017267700150615326394159909466200116916687 --Mike --~--~---------~--~----~------------~-------~--~----~ 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 -~----------~----~----~----~------~----~------~--~---
