Does order of magnitude depend on the entire number or just decimal places?

So, does the entire number make up the order of magnitude or just the decimal places. I don't understand

What a strange statement! What number are you talking about? What "decimal places"? Do you know the definition of "order of magnitude"?

For example if I have 3.4 and .1, are these numbers of the same order of magnitude because they both go into the tenths place 10^-1, or are they different orders of magnitude because 3.4 is much larger than .1?
