When it says "E-5" it means that the decimal is moved back 5 places
So 7.984E-5
= 0.7984E-4
= 0.07984E-3
= 0.00007984 BTC
So 7.984E-5
= 0.7984E-4
= 0.07984E-3
= 0.00007984 BTC

You're right, the E-5 moves the decimal point.
7.984E-5 = 7.984 * 10^(-5)
The negative sign before the exponent makes the decimal point move 5 places to the left, so in fact that number represents a rather small BTC amount.
negative exponent -> smaller number
positive exponent -> bigger number

Just a simple question really, I don't understand it. I'm pretty sure it has something to do with decimal points? What does it all mean?!?!
