This operator computes the result of division of one operand by another.
exp1 / exp2
If the divisor evaluates to zero, a run-time error occurs. If the result of the expression is used as an integer value, the result of the division is truncated to the nearest integer value.
4 / 2 // evaluates to 2 3 / 2 // evaluates to 1 5 / 0 // a run-time error occurs
