the result yielded by a real number when divided by zero
The reciprocal function y = 1/x. As x approaches zero from the right, y tends to positive infinity. As x approaches zero from the left, y tends to negative infinity.
In mathematics, division by zero, division where the divisor (denominator) is zero, is a problematic special case. Using fraction notation, the general example can be written as
