连分数计算
ContinuedFraction[x,n]
Example
In[1]:= ContinuedFraction[Pi, 20]
Out[1]= {3, 7, 15, 1, 292, 1, 1, 1, 2, 1, 3, 1, 14, 2, 1, 1, 2, 2, 2,
2}
In[1]:= ContinuedFraction[47/17]
Out[1]= {2, 1, 3, 4}
Copy
C++
FromContinuedFraction
FromContinuedFraction[list]
从连分数项列表中构造一个数
Example
In[1]:= ContinuedFraction[47/17]
Out[1]= {2, 1, 3, 4}
In[2]:= FromContinuedFraction[%]
Out[2]= 47/17
In[3]:= 2 + 1/(1 + 1/(3 + 1/4))
Out[3]= 47/17
