#52 – Arithmetic Operators

All numeric types in C# support the following arithmetic operators.

Multiplicative operators

*   Multiplication
/   Division
%   Modulus

Additive operators

+   Addition
–   Subtraction

Some examples of using arithmetic operators:

 // Multiplication
 int n1 = 12 * 22;       // 264
 double d1 = 2.3 * 4.8;  // 11.04
 double d2 = 6.9 * 2;    // 13.8 (implicit cast)

 // Division
 int n2 = 7 / 5;     // 1  (truncated)
 double d3 = 6 / 8;  // 0  (int division, then cast)
 double d4 = 6.0 / 8;   // 0.75  (8 implicit cast to double)

 // Modulus
 int n3 = 7 % 5;     // 2
 int n4 = 10 % 2;    // 0
 int n5 = 2 % 10;    // 2
 decimal m1 = 2.2m % 1.2m;  // 1

 // Addition
 int n6 = 12 + 15;   // 27
 int n7 = -23 + 12;  // -11
 double d5 = 5.6 + -2.3;   // 3.3
 ushort ul1 = 0x1234 + 0x9999;  // 0xabcd

 // Subtraction
 int n8 = 5 - 12;    // -7
 decimal m2 = 4.24m - 1.01m;   // 3.23
