An overflow error in computing occurs when an arithmetic operation exceeds the maximum size that can be represented within a given number of bits. This typically happens in fixed-size data structures like integers in programming languages. When the result of an operation is too large to be stored, it results in an overflow error, which can lead to unexpected behavior or system crashes.
The formula to calculate the overflow error (OE) is:
\[ OE = (CV + I) - MV \]
Where:
Let's say the current value (CV) is 100, the increment value (I) is 50, and the maximum value (MV) is 120. Using the formula:
\[ OE = (100 + 50) - 120 = 30 \]
So, the overflow error (OE) is 30, indicating an overflow has occurred.
