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  KolmogorovSmirnov test; I need to know which of the following is significantly different from zero: 2.6488505967818445E4 2.4752235474300806E6 My real problem is what does E4 and E6 mean? is it 2.4752235474300806 "exponent" 6? Thanks for any help in advance.
