            Integer Numbers Regular expression:
This will check if a number is an integer.

Positive integers are all the whole numbers greater than zero: 1, 2, 3, 4, 5, ... .

Negative integers are all the opposites of whole numbers: -1, -2, -3,-4, -5, ... .

Zero is not a whole number with either a positive or negative value, and is not an interger.

Null or Empty values are not intergers.
