2.5 Arithmetic Operators

• Binary arithmetic operators are: +, -, *, /
• Integer division truncates any fractional part
• Modulus operator: %
• x % y produce the remainder when x is divided by y (zero when y divides x exactly)
• The % modulus operator cannot be applied to float or double
• The direction of truncation for / and the sign of the result for % are machine-dependent for negative operands 
• Precedence (lowest first) : + -, * / %, unary + -
• Arithmetic operators associate left to right
