Troubleshooting Exceptions: System.DivideByZeroException

A DivideByZeroException exception is thrown when there is an attempt to divide an integer or decimal value by zero.

Make sure the value of the denominator is not zero before performing a division operation.

Dividing a floating-point value by zero results in either positive infinity, negative infinity, or Not a Number (NaN), according to the rules of IEEE arithmetic. Floating-point operations never throw an exception.
