====== Division by Zero (DIV/0) ======
[[dido:public:ra:xapend:xapend.a_glossary:start| Return to Glossary ]]

**Division by Zero** is the operation of taking the quotient of any number **''x''** and 0, i.e., **''x/0''**. The uniqueness of division breaks down when dividing by zero, since the product **''0·y=0''** is the same for any **''y''**, so **''y''** cannot be recovered by inverting the process of multiplication. 0 is the only number with this property and, as a result, division by zero is undefined for real numbers and can produce a fatal condition called a **Division by Zero** error in computer programs.
