Annotation of OpenXM_contrib/pari-2.2/COMPAT, Revision 1.1.1.1

1.1       noro        1: This file lists the incompatible changes between Version 2.x and older versions
                      2:
                      3: %%%%%%%%%%%%%%%%%%%%%%%%%%%% VERSION 2.2 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
                      4:
                      5: * The calculator GP:
                      6: ====================
                      7:
                      8: * The library PARI:
                      9: ===================
                     10:   - gsize() renamed to sizedigit()  [conflict with gtk]
                     11:   - hnfhavas removed (didn't work properly, hnflll provides an alternative)
                     12:
                     13: %%%%%%%%%%%%%%%%%%%%%%%%%%%% VERSION 2.1 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
                     14:
                     15: * The calculator GP:
                     16: ====================
                     17:  - most function names have changed (see misc/new.dic or use whatnow under GP)
                     18:  - lowercase / uppercase letters distinguished.
                     19:  - the syntax \var = value is not recognized anymore. Use standard
                     20:    metacommands instead.
                     21: (setting the compatibility level "compatible" to 3, with "default" will give
                     22: you those three back).
                     23:
                     24:  - strict parenthesis matching before executing the command
                     25: (set strictmatch to 0 to get old behaviour)
                     26:
                     27:  - functions label / goto have been removed (use break/next/return instead).
                     28:  - conjugation x_ has been removed. '_' can be freely used in identifiers.
                     29:  - \k metacommand removed
                     30:
                     31:  - result history is now cyclic (older results are erased when the maximal
                     32:    size "histsize" is reached).
                     33:  - the Set() function turns objects into strings (so that set functions are
                     34:    able to treat arbitrary objects). Use eval to turn them back to GENs.
                     35:  - the type() function returns a string and not a number.
                     36:  - sum(X=a,b,...,x) yields x if b<a. Analogous statement for prod.
                     37:
                     38: * The library PARI:
                     39: ===================
                     40:  - use symbolic type names (t_INT, etc.). Don't use any explicit type number
                     41:    in your programs since these are liable to change (they have not, but will).
                     42:  - the codewords of GEN objects have a different internal structure. The
                     43:    components should only be accessed through the documented macros. When
                     44:    creating codeword x[1] for the GEN x, use the eval* macros (the set* ones
                     45:    don't fill the codeword completely).
                     46:  - the following constant names have changed ("pari" prepended): C1, C2, C3, K,
                     47:    K1, K2, K4. The constant C31 has disappeared.
                     48:  - prec and defaultpadicprecision are no longer global. The latter has
                     49:    disapeared.
                     50:  - char *pariversion not set anymore (use the macros PARIVERSION/PARIINFO)
                     51:  - LONG_IS_32BIT is never defined (test whether LONG_IS_64BIT is defined
                     52:    or not).
                     53:  - gen2str() renamed to GENtostr().
                     54:  - gitoascii() suppressed, use GENtostr().
                     55:  - init() renamed to pari_init().
                     56:  - the macro mant() has been suppressed.
                     57:  - imprimer() suppressed. output() is now a function and can be used under
                     58:    all debuggers.
                     59:  - the prototypes and behaviour of gredsp() and normalize() have changed.
                     60:    They are not documented anymore.
                     61:  - the install() function has been modified (use codes instead of valence).
                     62:  - gpuigs only has two arguments.
                     63:  - integ now takes two arguments, like deriv.
                     64:  - setrand, getrand, getstack, gettime, glength return a C long, and not a GEN.
                     65:  - pari_randseed no longer global, use setrand/getrand
                     66:  - gerepile(ltop,lbot,0) no longer returns ltop - lbot
                     67:  - nf[5][7] stored in two element form (was Z-basis) for faster inversion
                     68:  - t_POL and t_POLMOD can be freely mixed as long as main variables are the
                     69:    same (result is the expected POLMOD)
                     70:
