The largest "number" you can store in IEEE754 double precision is Infinity, the smallest is -Infinity.

If you mean non-infinite representations, then that would be roughly

±1.7976931348623157 x 10^³⁰⁸.

See here for an excellent answer regarding IEEE754 formats. See here for a wikipedia article showing the representation.
