Questions tagged [divide-by-zero]

Division by zero is the division by any value that is exactly equal to 0 -- a computation with an undefined result.

In computing, a program error may result from an attempt to divide by zero. Depending on the programming environment and the type of number (e.g. floating point, integer) being divided by zero, it may generate positive or negative infinity by the IEEE 754 floating point standard, generate an exception, generate an error message, cause the program to terminate, or result in a special NaN (not a number) value.
