Is 7.0 an integer?

Hello,

I have requested the script for my physics paper, and there was one question where I'm not sure whether they made a mistake or not.

The answer in the mark scheme is: "7 (an integer)"
My answer was "7.0"

Should I be awarded the mark or not?

7 = 7.0. How you write the number doesn't change the fact that it's an integer. But if they wanted you to understand that the answer was a whole number because of the nature of what it's describing (i.e. it's a discrete quantity), e.g. number of bounces (you can't have have 7.2 bounces), rather than by coincidence, e.g. velocity happens to be exactly 7.0 m/s from data given, then they might not

What was the question?

Same thing mathematically, but physically 7.0 might be an indication of your degree of accuracy, which might not be in context.

Since you've neglected to include the question; how the hell should we know?

The question was: "Calculate the number of electrons causing the charge on the droplet."

The lowest number of significant figures going into the calculation was 2.
