Hi all, Is there a way to compute a math expression on any buffer? I mean, if I have a buffer with the following expression2 + 3I want to mark the region and compute the result 2 + 3 = 5 It doesn't seems too hard to do, I've looked on calculator.el for a"computing" function I can call but I didn't find it.
Try with embeded mode of calc: C-x * E (no need to mark the region) and similar commands (J or W in place of E). You need to type C-x * E again to exit the embeded mode. Another solution: - mark the region with math expression and put it into kill-ring (M-w) - type SPC = SPC - run the calc (C-x * c) - type ' (apostrophe) and yank yor math expression (C-y) - type RET - type y (or C-x * y) to copy the result into buffer - exit calc (q) regards marc
