how can I calculate big numbers?

[agent.smith]

hi, I've found some examples of calculating bigger then 32-bits integer numbers, but there wasn't exaples of float calculations.
Can somebody help, by suppling me with link or some hint?

thanks, in advance.

I'm not Mr Calculamatron but maybe 64 bit int's may be a solution?

[agent.smith]

no, int64 is not a solution. i was talking about general algorithm for calculation of large numbers. something like you have two n-bit numbers and want to define the operations for them (addition, substraction, multiplication, division, etc)

Have a look at the GNU MP library (http://www.swox.se/gmp/).
