#55 – Integer Division Results in Truncation

When dividing one integer by another using the division operator, C# always rounds the result towards 0 — i.e. truncates.

 int n1 = 7 / 2;       // 3
 long n2 = -7 / 2;     // -3
 short n3 = -11 / -3;  // 3

If an attempt is made to divide by zero, an exception of type System.DivideByZeroException is thrown.

If you try to divide by the literal 0, you’ll get an error at compile time.
