NAME

       numprocess - This program mutates numbers as it encounters them.

SYNOPSIS

       numprocess [-dhV] /<expression>/ [FILE or STDIN]

       | numprocess [-dhV] /<expression>/  (Input on STDIN from pipeline.)

       numprocess [-dhV] /<expression>/    (Input on STDIN.  Use Ctrl-D to stop.)

DESCRIPTION

       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.

USAGE EXAMPLES

         Add 1 to all numbers.

          $ numprocess /+1/ file1

         Convert all numbers from miles to kilometers.  Multiply by 8 and divide by 5.

          $ cat file1 | numprocess /*8,%5/

         Convert from celcius to fahreheit degrees.  Multiply by 9, divide by 5 and add 32.

          $ numprocess /*9,%5,+32/ temperatures

         Find the area of each circle from the given radius.

          $ numprocess /^2,*pi/ radii

KEYWORDS AND OPERATORS

          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.

BUGS

       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.
