Double tye question

"The values of double type may range from -1.7 * e-308 to 1.7 * e308".

Can someone clarify this statement for me. Thanks

I don't think that was written properly. But as it's written...


-1.7 x 10 ^ (-308) to 1.7 X 10 ^ 308

or roughly a really small number and a really big number.

Thanks. RR
