如果您有 a=8, b=2, m=2，那么您就有 a/b mod m = 8/2 mod 2 = 4 mod 2 = 0 和(a mod m)/(b mod m) = (8 mod 2)/(2 mod 2) = 0/0 = NaN NaN 不等于0。
No.
If you have a=8, b=2, m=2 then you have a/b mod m = 8/2 mod 2 = 4 mod 2 = 0 and (a mod m)/(b mod m) = (8 mod 2)/(2 mod 2) = 0/0 = NaN NaN is not equal to 0.

不。
如果您有
a=8, b=2, m=2，那么您就有a/b mod m = 8/2 mod 2 = 4 mod 2 = 0和
(a mod m)/(b mod m) = (8 mod 2)/(2 mod 2) = 0/0 = NaNNaN不等于0。No.
If you have
a=8, b=2, m=2then you havea/b mod m = 8/2 mod 2 = 4 mod 2 = 0and
(a mod m)/(b mod m) = (8 mod 2)/(2 mod 2) = 0/0 = NaNNaNis not equal to0.这个恒等式不成立。这是一个反例：
因此你的身份不成立。然而，我几乎可以肯定，如果 m 和 b 互质，则它成立。
This identity does not hold. Here is a counter-example:
Thus your identity does not hold. However, I am almost certain that it will hold if m and b are relatively prime.
