A whole number is a number that has no decmials. Can be + or -. Whole number are 4,2,23,3535, etc. Numbers such as 4.2,5.5, etc are not.The term whole number is one you’ll find often in mathematics. You may also see the term integer or natural number used in the same manner. Essentially the definition of a whole number is based around what it doesn’t contain. A whole number can’t be a fraction of a number, a percentage, or have a decimal. If you have a number like 21.32, it has a whole number portion (21). But in itself, this number is not a whole number because it contains a fraction (.32).
