Unlike floating point numbers, integers cannot have decimal places. Integers are a commonly used data type in computer programming. Integers are essential numbers in mathematics. Integers help in computing the efficiency in positive or negative numbers in almost every field. Integers let us know the position where one is standing. It also helps to calculate how more or less measures to be taken for achieving better results
