Yes. A whole number is any positive number including zero. Let's say you want to use the whole number 47. The scientific notation for 47 is 4.7 times 101. You can put any number into scientific notation except fractions. You would have to change the fraction to a decimal (if possible) before you could put it into scientific notation.
