Batch Percentage Help

  • 2

Hello,
I need some direction in how to get the percentage of two variables in batch. The problem im having is that decimal values less than 0 return a 0 making it impossible to calculate the percentage, or am i just missing something?

      the closest you can get is vbscript, which is native to windows. You can write your own calculator using whatever degree of elaboration you have the patience for.
      here’s a simple one (calc.vbs):
      set con=wscript.stdin
      set xx=wscript.stdout
      set t=wscript.arguments
      op=t(1)
      one=t(0)
      two=t(2)
      select case op
      case “/”
      out=one/two
      case “+”
      out=one+two
      case “-“
      out=one-two
      case “*”
      out=one*two
      end select
      xx.writeline(out)
      end

      and call it like this (to capture the answer to a var):
      for /f %%a in (‘cscript /b calc.vbs 12.6 / 18.2’) do set xx=%%a
      echo %xx%
      ::—– end
      I was lazy and used separate arguments, so the spaces required between the numbers and operators.
      of course you can add as many other operators as you want:
      modulo, exponentiation, square roots, etc etc.
      I wish cscript could be compiled into .exe, but alas…
      i saw some for download but they were either “trials” or $$.
