SYNOPSIS

numprocess [-dhV] /<expression>/ [\s-1FILE\s0 or \s-1STDIN\s0]

| numprocess [-dhV] /<expression>/ (Input on \s-1STDIN\s0 from pipeline.)

numprocess [-dhV] /<expression>/ (Input on \s-1STDIN\s0. 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.
