测试了一下，要进行高精度计算需要用 字符串 表示数字
然后定义 prec 的值，示例代码如下，你想用多高精度都行

------

from decimal import *

getcontext().prec = 180


x = "4.26000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000032"

y = "2.13000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000021"


print(Decimal(x))

print(Decimal(y))

z = Decimal(x) + (Decimal(y))

print(z)



【 在 feng321 (sfdf) 的大作中提到: 】
: a=2.1
: b=3.2
: print(a+b)
