Integers are only whole numbers and include both positive as well as negative whole numbers and 0. An integer cannot not have a decimal or a fractional part. The set of integers is {... −2, −1, 0, 1, 2, ...}

When one integer is divided by another integer, the result may be a fraction or a decimal. Though it should be kept in mind that not all decimal numbers can be expressed as one integer divided by another. Irrational decimal number like the square root of 2 and pi cannot be expressed as the quatient of one integer divided by another.
