OTHER types data.

[compsystems]

Hello BP

using the getType() command for the TABLE data type, throwthe word OTHER

What other types of data exist in Xcas outside of those listed?

Thank you

getType(5.0) [enter] NUM

getType(5) [enter] NUM

getType(3+4*i) [enter] EXPR

is_matrix([[1,2],[3,4]]) [enter]  True

getType(f(x):=x+1) [enter] FUNC

phonebook_17:= table("John" : 938477566,"Jack" : 938377264,"Jill" : 947662781)

getType(phonebook_17) [enter] OTHER

getType(9999999999999999999) [enter] OTHER

type returns DOM_MAP for a table, not OTHER.
Cf dispatch.h for all giac types:

_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
_POINTER_=20, // void * _POINTER_val
_FLOAT_=21 // immediate, _FLOAT_val

Hello

I use getType() or type() or subtype() according to the context

an improvement with getType

getType(9999999999999999999) [enter] "OTHER"

group it as "NUM"

getType(9999999999999999999) [enter] "NUM"
getType(5.0) [enter] "NUM"
getType(5) [enter] "NUM"
getType(3/4) [enter] "NUM"
-------------------------------------------------

and for a table

phonebook_17:= table("John" : 938477566,"Jack" : 938377264,"Jill" : 947662781)
getType(phonebook_17) [enter] "OTHER"
getType(phonebook_17) [enter] "TABLE"

[parisse]

getType is a TI compatibility instruction, please use type instead.

From the input line I can generate the following types, please BP, you can add an example for the types of missing objects (1 (int val), 3 (_REAL), 9 (_SPOL1), 11 (_EXT), 14 (_ROOT), 15 (_MOD), 18(_EQW), 19 (_GROB) , etc) in the following list.

Thanks

_REAL : evalf(pi,30)
_MOD: 3 mod 5
other types are intended for internal use. For example internally there are two types of integers: CPU integers (type _INT_==0) and long integers (type _ZINT==2).
