1、On Factorial Polynomial
關于階乘多項式

2、Now, let's return to the factorial function.
現(xiàn)在，讓我們回到階乘函數(shù)上來。

3、Write a function that calculates a number's factorial using recursion.
寫出一個用遞歸來計算階乘的函數(shù)。

4、Results will later be displayed in the labels beneath the factorial buttons.
結果稍后將顯示在階乘按鈕下方的標簽中。

5、What you want to do with this value in register 3 is to calculate the factorial of it.
在寄存器3中想要做的是計算此值的階乘。

6、According to the decomposition method, a majority of the factorial using arrays to achieve.
按分解的方法，將一個大數(shù)的階乘用數(shù)組實現(xiàn)。

7、If you've written factorial code, you've probably noticed that the code is still wrong.
編寫了階乘代碼后，您可能發(fā)現(xiàn)該代碼仍有錯誤。

8、That is, now we have to divide by NA factorial times NB factorial.
就是說，現(xiàn)在我們要除以NA的階乘乘以nb的階乘的積。

9、This limits greatly the possible range of your factorial function.
這極大地限制了階乘函數(shù)的可能范圍。

10、Then, because num is greater than 0, factorial will be called again, this time with 3.
然后，由于 num大于0，因此會再次調用factorial，不過這次是計算 3 的階乘了。

11、Therefore, you need to pass it as the first parameter to the factorial function.
因而，需要將其作為第一個（也是惟一一個）參數(shù)傳遞給factorial函數(shù)。
