Usage:

1. When both dividend and divisor are integers, the result is also an integer.

For example, the result of 1/2 is 0 and that of 9/2 is 4.

2. When the dividend or divisor is a floating point number, the result is a floating point number.

For example, the result of 1.0/2 is 0.5000000000 (double precision type), and the result of 9.0/2.0 is 0.500000000000 (double precision type).
