在目前所发表的十六进制转化成BCD码的处法中，一般都采用移位相加的方法，其计算过程都比较费时，不适宜很多场合，且很多不适宜C语言调用。而在C语言中，有些初学者用求余的方法来做这种运算，造成程序十分臃肿。下面这段程序仿照竖式除法来进行运算，速度超快。-Published in the current hex code into a BCD at law, in general, have adopted the method of shifting the sum of its calculation is relatively time-consuming and not suitable for many occasions and many of them not suitable for C language calls. In the C language, some beginners seeking more than the method used to do this operation, resulting in a very cumbersome process. This procedure along the lines of the following vertical division to carry out operations, super-fast.
