numprocess - This program mutates numbers as it encounters them.

       There is currently no way to take the number found in the text stream and use it as the numerator instead
       of the denominator of a division operation.  Workaround: https://bugs.debian.org/553913

       numprocess is part of the num-utils package, which is copyrighted by Suso Banderas and released under the
       GPL license.  Please read the COPYING and LICENSE files that came with the num-utils package

         Developers can read the GOALS file and contact me about providing
       submitions or help for the project.

numprocess will take as one argument, a list of operations to be performed on numbers that it encounters.
       It will perform those operations on each number and return the result in place of the original number.

          For operators, the modifying number goes directly after the operator, with
          the exception of functions like sqrt, sin, cos, etc.

          +     Addition
          -     Subtraction
          *     Multiplication
          %     Division
          ^     Power function
          sqrt  Square Root  (*)
          sin   Sine function
          cos   Cosine function

          Constants and keywords that can be used

           pi    3.141592654
           e     2.718281828

         (*) When using the sqrt operation on negative numbers, it will take the
            absolute value of the number, sqrt it and then tack an i on the end
            of the result to signify that the resulting number is imaginary.
