217.152302 millions ?

If I am interpreting the question correctly, I believe you are looking for perhaps the full number of 217.152302 Millions?

In this case, this question is easy. As Million is a unit, and you wish to convert it to a whole number, you will need to substitute a number for the unit "millions" In this case, it would be 1,000,000. So let us substitute!

$${\mathtt{217.152\: \!302}}{\mathtt{\,\times\,}}{\mathtt{1\,000\,000}}$$

Now, instead of going to that calculator beside you. Let me teach you a method. 

Because the number is disible by 10. You can use this special method.

Depending on now many 0's are in the number, you will need to move the . (Decimal Point) to the Right.
Lets use 1,000,000!

How many 0's are in there?

6?

I think so too!

Lets move the Decimal point to the right 6 times!

217.152302

to

217152302. (This is what it should look like)

Now, then we look at any number that ISN'T a 0 and multiply it by it.

In this case, it is a 1.

So...

$${\mathtt{217\,152\,302}}{\mathtt{\,\times\,}}{\mathtt{1}}$$

This would still equal to 217152302

Therefore, the answer you are looking for is 217152302
