Re: [igraph] Question about Eigenvector centrality

[Gábor Csárdi]

Hi,

it is called scientific notation, essentially 5.2e-2 means 5.2 times
10 to the power of -2: 0.052. See
http://en.wikipedia.org/wiki/Scientific_notation#E_notation

Btw. I cannot run your code, because I don't have your data. A
reproducible example needs data, see e.g.
