 ## 1.1 - Overview
 COJAC is in fact a two-fold tool:

+- a *_"numerical sniffer"_* that detects anomalies arising in arithmetic operations, 
 on either integers (eg overflow) or floating point numbers (eg 
 cancellation or NaN outcome). This can be of great help to detect vicious bugs

+- an *_"enriching wrapper"_* that automatically converts every float/double data 
 into richer number types, so that you can experiment, at a very low cost, some
 beautiful models such as arbitrary precision numbers, interval computation,
 or even the marvelous automatic differentiation.

 With COJAC you don't have to modify your source code or even recompile. All 
 the work is done at runtime, when your application gets instrumented on-the-fly.
