Positive zero and negative zero are concepts in computing and mathematics, particularly in floating-point representation. Positive zero is represented as +0.0, while negative zero is represented as -0.0. They are distinct values in certain contexts, such as in IEEE 754 floating-point arithmetic, where they can yield different results in calculations and comparisons, particularly with operations like division. For example, dividing a positive number by positive zero yields positive infinity, while dividing by negative zero yields negative infinity.
