Working with really huge numbers in MATLAB?

I need to manipulate numbers with a bit length of nearly 192 bits. It also involves exponentiation to said bit length. How do I manage this in MATLAB?

[John D'Errico]

You can use my VPI tool, as long as the numbers are integer. It can handle exponentiation, in fact, I even included an overloaded exp there, giving you only the integer part of the result of course. I've been playing with a variable precision decimal form too, but it is at least a few weeks away from done.

yes thank you. i have downloaded the vpi tool and am using it. it works wonderfully well. thank you once again!

You either need to use the Symbolic Mathematics Toolkit, or the Matlab File Exchange contribution for Variable Precision Integers

Large numbers (up to 65535 bits) can also be used with the Fixed Point Toolkit, but that toolkit does not handle exponentiation.

Convert your numbers to variable precision arithmetic using vpa.

[Walter Roberson]

That requires the Symbolic Math Toolkit
