Default What minimum exponent would give 100M digit prime?

Hello All,

What minimum exponent value would give a 100M digit prime?

Also is there a calculator on the internet or that I could download that could give me the specific number that any exponent I use in the formula 2^P - 1?

Like to calculate the value of:

2^49254458 - 1?

Of course my computer's calculator gives infinity!!!!!

Thanks.
