Operators

Operators are used to operate on values. They can be grouped into five types: arithmetic, assignment, comparison, logical and bitwise operators.

Arithmetic operators

There are the four basic arithmetic operators, as well as the modulus operator (%) which is used to obtain the division remainder.

float x = 3+2; // 5 // addition      x = 3-2; // 1 // subtraction      x = 3*2; // 6 // multiplication      x = 3/2; // 1 // division      x = 3%2; // 1 // modulus (division remainder)

Notice that the division sign gives an incorrect result. This is because it operates on two integer values and will therefore round the result and ...
