我在主程序中，循环执行下面的一组计算程序，经常会出错，这可能是什么原因导致的了。
wRTempValue = (int)((long)(dwROutputVoltCalValue * 10 >> 12) * 4963 >> 9);
wROutputVoltNew = (int)((long)(wRTempValue) * 9099 >> 13);
wROutputVoltNew = (int)((long)(wRTempValue) * 9099 >> 13);
wSTempValue = (int)((long)(dwSOutputVoltCalValue * 10 >> 12) * 4963 >> 9);
wSOutputVoltNew = (int)((long)(wSTempValue) * 9099 >> 13);
wTTempValue = (int)((long)(dwTOutputVoltCalValue * 10 >> 12) * 4963 >> 9);
wTOutputVoltNew = (int)((long)(wTTempValue) * 9099 >> 13);
