description

This plugin sums up a visual (block) selection of numbers and echoes the result. Arithmetic operators: ^ ** * % / - + (). Math functions: sqrt, log, log2, log10, exp, abs, sin, cos, tan, base. Hex numbers start with 0x, and binary numbers with 0b. Math functions can be abbreviated to the first letter of the function name, except r=sqrt, l2=log2, l10=log10. Without an operator the addition sign is added between numbers. Characters not a number, operator or math function are ignored, as well as any character between brackets to support commenting. After visual (block) selection press 't' to echo the sum on the command line. In insert mode press Alt-= to insert the value of the last expression found on the current line. If you want to use other keys to calculate the sum, please add the following to your .vimrc, and replace <A-a> with the desired key sequence:     vmap <A-a> <PLUG>SumOfSelectionLastSelection     imap <A-a> <PLUG>SumOfSelectionLastExpression The number of decimals can be configured by adding:     let g:sumofselection_nrofdecimals = [Nr of decimals] A negative number means full precision. The default value is 2 decimal places. The rounding method is set to 'common' (i.e. half round up). The result is stored in the unnamed register "" and register "0.  You can paste the result in normal mode with p or "0p. And in insert mode with <C-r>0. The sum is stored in register "s. Example usage in insert mode:               2^10 = [ Press Alt-= ] Result:  2^10 = 1024               2^10 = 1024 / 8 = [ Press Alt-= ] Result:  2^10 = 1024 / 8 = 128 Example of possible sums for visual block selection:            (10          12 * 5.5     12.52             20          25 * 2.5     17.59             30)*2     32 * 4.5     15.45 Shorthand:            r144 / r16  =  sqrt(144) / sqrt(16)            l2               =  log(2)            l2 0x400   =  log2(0x400)            b1966,62  = Vi            b2^10,16  = 0x400            b0xf,2       = 0b1111 Please note that due to regex restrictions brackets can't be used inside the argument to log2 and log10 e.g. l2(r(64)) != l2(r64).
