Multiplicative Inverse of 821

Multiplicative Inverse of 821 is defined as what you can multiply with 821 to get 1.
If the Multiplicative Inverse of 821 is x, the problem can be written as a function as follows:
821(x) = 1
Thus, to get the answer, we divide 1 by 821 like this:
1 / 821 = 0.00121803
Note that the answer is rounded to the nearest 8 decimals if necessary. We can prove that the answer is correct: 0.00121803 multiplied by 821 equals 1.
The Multiplicative Inverse of postive 821 has a positive answer and the Multiplicative Inverse of negative 821 has a negative answer. Therefore, the Multiplicative Inverse of -821 is -0.00121803.
