CAS: log of large integers?

[parisse]

5 stands for multivariate polynomials, 9 sparse univariate series expansion, 11 for algebraic extensions. They are intended for internal use, you can access them from Xcas but some commands to manipulate them are not available on the Prime.
The complete list of giac types is in dispatch.h:

Code:


  enum gen_unary_types {
    // immediate type (without mem allocation) should be < _ZINT
    _INT_= 0, // int val
    _DOUBLE_= 1, // double _DOUBLE_val
    // all type below or equal to _DOUBLE_ must be non pointers
    _ZINT= 2, // mpz_t * _ZINTptr
    _REAL= 3, // mpf_t * _REALptr
    // all type strictly below _CPLX must be real types
    _CPLX= 4, // gen * _CPLXptr
    _POLY= 5, // polynome * _POLYptr
    _IDNT= 6, // identificateur * _IDNTptr
    _VECT= 7, // vecteur * _VECTptr
    _SYMB= 8, // symbolic * _SYMBptr
    _SPOL1= 9, // sparse_poly1 * _SPOL1ptr
    _FRAC= 10, // fraction * _FRACptr
    _EXT= 11, // gen * _EXTptr
    _STRNG= 12, // string * _STRNGptr
    _FUNC= 13, // unary_fonction_ptr * _FUNCptr
    _ROOT= 14, // real_complex_rootof *_ROOTptr
    _MOD= 15, // gen * _MODptr
    _USER= 16, // gen_user * _USERptr
    _MAP=17, // map<gen.gen> * _MAPptr
    _EQW=18, // eqwdata * _EQWptr
    _GROB=19, // grob * _GROBptr

    _FLOAT_=21 // immediate, _FLOAT_val
  } ;
