用下面这个公式计算零点效率非常高：\begin{align} \frac{1}{1-2^{1-s}} \sum_{n=0}^{\infty } \left (
\frac{1}{2^{n+1}} \sum_{k=0}^{n} \frac {\left ( -1 \right ) ^{k}} {\left ( k+1 \right )^{s} } \binom{n}{k} \right ) \end{align} 比 \begin{align}\frac{1}{1-\frac{2}{2^{s}} } \sum_{n=0}^{\infty }\frac{ \left( -1 \right ) ^{n-1}}{n^{s}}\end{align} 要快很多。python代码：def zeta(s):
E = 1e-10
res = 0+0j
n = -1
while True:#first sigma
n += 1
kk = 0+0j
comb = 1
for k in range(n+1):#second sigma
kk += comb * (k+1) ** -s
comb *= (k-n) / (k+1)
kk *= 2 ** - (n+1)
res += kk
if abs(kk) < E:
# print(n)
break
return res / (1 - 2 ** (1-s))
print(zeta(0.5+1j*14.13472514173500016454))}
