Metrics - difference between 0 and null?

Hi everyone!

I've made some calculations on my network (eigenvector, degree, etc.) and for some nodes i got the result 0 and null (and by null i mean i got nothing - blank record).

What is the difference between those two outcomes?

Hi G Sudhir S,

I am running eigenvector centrality in stream mode and am getting all null values returned. You indicate that the function returns null if a condition is met. What condition when met returns null values? Thank you for your help.
