/**
 * CHaotic Arithmetics O Shit  version 0.666
 * This is one of the most boring programs I've ever written.
 * It expects two floating-point numbers as arguments. Each argument is
 * doubled 30 times, (only the fractional part) that is. The results 
 * are anything but amazing. Won't explain more, I can't believe I'm writing
 * this. 
 * 
 * To compile use your favorite ISO-C++ compliant compiler. 
 * No GUI, no nothing. Not even meaningful identifiers. 
 * In fact, you must be outa your mind to have downloaded this. 
 * Adding a license would clearly count as hubris. 
 * Have fun(?)... yeah right!
