Question

On a typical Ubuntu (10.4 in this case) desktop how can I do “to the power of” or “exponent” calculations?

So for example I want to know 2^80, Google calculator shows “2^80 = 1.20892582 × 1024” and I’m too lazy to type all my sums in there and then convert them to the full answer.

I have bash (bc/expr), C & C++ installed, as well as a browser so I have JavaScript at my disposal, and I have php-cli installed.

I must be able to use on of these via the command line to perform the exponent sums like a calculator? Just parsing the sum as a one liner?

Everything I do comes out as the abbreviated answer like Google.

Answer 1

This isn’t really on topic, but

echo "2^80" | bc
