Basic calculations can done within vim easily by typing (insert-mode): STRG (=CTRL) + R followed by = then for example 2+2 and hit RETURN the result 4 will be printed in the document. Some other tipps you can find under www.linuxclass.de/vim.phtml

Adding the following map to your vimrc ino <C-A> <C-O>yiW<End>=<C-R>=<C-R>0<CR> Then, just type 8*8<C-A> you will get 8*8=64

For simple arithmitic, you can often get away with just using repeats of the Ctrl-A (increment) and Ctrl-X (decrement) commands. For instance, to calculate 453-244, insert the text "453" and then, in Command mode, type 244 and press Ctrl-X (answer: 209). To calculate 4024+3322, insert the text "4024" and then, in Command mode, type 3322 and press Ctrl-A (answer: 7346).

Is there any way that I can calculate with real numbers (as opposed to integers only)?

I have a mapping for passing a line to bc: map gbc yypkA =<ESC>jOscale=2<ESC>:.,+1!bc<CR>kJ I guess it could be made a bit better. Another 'useful' mapping I once needed was summing numbers on multiple lines: vmap gs y'>p:'[,']-1s/$/+/\|'[,']+1j!<CR>'[0"wy$:.s§.*§\=w§<CR>'[yyP:.s/./=/g<CR>_j So, having 10 20 30 in a file would result in two new lines: == 60
