HP Prime CAS & Large numbers

[parisse]

There is indeed a max for integers, in global.cc

Code:


  double powlog2float=1e4;
  int MPZ_MAXLOG2=8600; // max 2^8600 about 1K

As far as I remember, the long integer library is not optimal for integer operations (it uses Karatsuba multiplication, not FFT), if you multiply/divide really large integers it will be slow. There is always a trade-off between speed and size limits, and I tend to be conservative. I don't remember when the limits were set, if it's an heritage of the hp39gii, then they should probably be raised, perhaps multiplied by 10.
