Question

Quizplus · Accepted Answer

The given expression can be simplified as 2^(-126), which is a very small positive number (close to 0) since the exponent is negative. Any positive number greater than this value would result in a positive overflow, which occurs when the result of a computation is too large to be represented in the given number of bits. Therefore, the best choice is B - positive overflow.
