Expecting a reasonable answer.

You have a number, which you may be expecting to be a counting number

(integer) which has 308 decimal places. If we convert that to base 2,

it will be some huge number of bits. Octave might be using 8 bytes to

represent a number. Nowhere near the size you need.

Work with much smaller numbers, and slowly increase them. Look at how

the error scales with the size of the number.
