    All libraries except native float setted to precision with 31 decimal digits. <br/>
    To increase DoubleJs_Static performance we used static methods and .sqr() insted of .mul() in some places. <br/>
    To increase BigJs and BigNumberJs we used .round(31) and .dp(31) after each multiplication without this they become x1000 slower.<br/>
