how can I explain a p-value of 1.59461E-70 in excel?

Question

I calculated the p-value in the excel sheet and it was presented as

1.59E-70

so, what does this means or how it is explained?

Answer 1

This is a very small number. Excel works to a certain finite accuracy in its calculations so what in reality is a value of zero may be presented as a very small number. E-70 is the scientific way of writing ×10^-70, an extremely small number (69 zeroes after the decimal point). So p=0 is what it means.
