Ratiobalance

I needed something to balance numbers to certain percentages, but only with addition. The math was not convenient in a calculator, so I made this program to do it for me. It's neat with some good information, showing the differences too.

ratiobalance 512.12 522 12 -r 53 45 2
=====================================Values=====================================
01: 000000512.12                =>      48.95%
02: 000000522.00                =>      49.90%
03: 000000012.00                =>      1.15%
====================================Analysis====================================
total                           :       1046.12
optimizing                      :       02 (522.0 => 49.90%)
new 1%                          :       11.6
new 1% * rat(2)                 :       522.0 = 522.0
=====================================Result=====================================
01: 0000614.8000 (102.68)       =>      53.00%
02: 0000522.0000 (00.00)        =>      45.00%
03: 0000023.2000 (11.20)        =>      2.00%
================================Result Analysis=================================
factor for added                :       1.00
new total                       :       1160.00
total diff                      :       113.88
================================================================================

For cases where you don't want to keep the ratio but rather changed the added amount, you can use the -f option to multiply the amount that gets actually added by some factor. So if the total diff shows 113.88 as in the example, but you want to remain under 100 changed, try around with the -f option until you have reached a satisfactory result.

Please note that using the -f option may make the ratio imperfect again and that numbers are implicitly rounded to two comma values.
