long _IQint( _iq A)和_iq _IQfrac( _iq A) ，当A为负数时，得到的结果和手册讲得不对，如下的代码，请问是我下面写的程序有问题吗

_iq Y0 = _IQ(2.3456);  
_iq Y1 = _IQ(-2.3456);  
long Y0int, Y1int;  
_iq Y0frac, Y1frac;

Y0int  = _IQint(Y0);   // Y0int = 2  
Y1int  = _IQint(Y1);   // Y1int = -2  
Y0frac = _IQfrac(Y0);   // Y0frac = 0.3456  
Y1frac = _IQfrac(Y1);   // Y1frac = -0.3456

GUI_DispFloatFix (Y0int,9,4);GUI_DispString(" ");//显示为0002.000
GUI_DispFloatFix (Y1int,9,4);GUI_DispString(" ");//显示为-003.000
GUI_DispFloatFix (_IQtoF(Y0frac),9,4);GUI_DispString(" ");//显示为0000.3456
GUI_DispFloatFix (_IQtoF(Y1frac),9,4);GUI_DispString(" ");//显示为0000.6544 此帖出自小平头技术问答
