Basic math?

Hi,

I'm having some trouble with what I believe is basic math - I just can't remember what to do here...

I'm doing stats - Kolmogorov-Smirnov test; I need to know which of the following is significantly different from zero:

2.6488505967818445E-4

2.4752235474300806E-6

My real problem is what does E-4 and E-6 mean? is it 2.4752235474300806 "exponent" -6?

Thanks for any help in advance.

Re: Basic math?

2.0E-4 means 0.00020
2.1E-6 means 0.0000021

Understand?
