Arithmetic Operators

• The type of result is determined by the types of operanda, not their values.
• This rule applies to all intermediate results in expression.
• If one operand is an int and another is a double, the result is a double; if both operands are ints, the result is an int.

Integer Arithmetic

• When both operands are integers, the expression is an integer expression, the operation is integer arithmetic.
• For modulo division (%), the sign of the result is always the sign first operand.

Real Arithmetic

• When both operands are real, the expression is a…
