Annotation of OpenXM_contrib/pari/COMPAT, Revision 1.1.1.1

1.1       maekawa     1: This file lists the incompatible changes between Version 1.39.15 and 2.0.x
                      2:
                      3: * The calculator GP:
                      4: ====================
                      5:  - most function names have changed (see misc/new.dic or use whatnow under GP)
                      6:  - lowercase / uppercase letters distinguished.
                      7:  - the syntax \var = value is not recognized anymore. Use standard
                      8:    metacommands instead.
                      9: (setting the compatibility level "compatible" to 3, with "default" will give
                     10: you those three back).
                     11:
                     12:  - strict parenthesis matching before executing the command
                     13: (set strictmatch to 0 to get old behaviour)
                     14:
                     15:  - functions label / goto have been removed (use break/next/return instead).
                     16:  - conjugation x_ has been removed. '_' can be freely used in identifiers.
                     17:  - \k metacommand removed
                     18:
                     19:  - result history is now cyclic (older results are erased when the maximal
                     20:    size "histsize" is reached).
                     21:  - the Set() function turns objects into strings (so that set functions are
                     22:    able to treat arbitrary objects). Use eval to turn them back to GENs.
                     23:  - the type() function returns a string and not a number.
                     24:  - sum(X=a,b,...,x) yields x if b<a. Analogous statement for prod.
                     25:
                     26: * The library PARI:
                     27: ===================
                     28:  - use symbolic type names (t_INT, etc.). Don't use any explicit type number
                     29:    in your programs since these are liable to change (they have not, but will).
                     30:  - the codewords of GEN objects have a different internal structure. The
                     31:    components should only be accessed through the documented macros. When
                     32:    creating codeword x[1] for the GEN x, use the eval* macros (the set* ones
                     33:    don't fill the codeword completely).
                     34:  - the following constant names have changed ("pari" prepended): C1, C2, C3, K,
                     35:    K1, K2, K4. The constant C31 has disappeared.
                     36:  - prec and defaultpadicprecision are no longer global. The latter has
                     37:    disapeared.
                     38:  - char *pariversion not set anymore (use the macros PARIVERSION/PARIINFO)
                     39:  - LONG_IS_32BIT is never defined (test whether LONG_IS_64BIT is defined
                     40:    or not).
                     41:  - gen2str() renamed to GENtostr().
                     42:  - gitoascii() suppressed, use GENtostr().
                     43:  - init() renamed to pari_init().
                     44:  - the macro mant() has been suppressed.
                     45:  - imprimer() suppressed. output() is now a function and can be used under
                     46:    all debuggers.
                     47:  - the prototypes and behaviour of gredsp() and normalize() have changed.
                     48:    They are not documented anymore.
                     49:  - the install() function has been modified (use codes instead of valence).
                     50:  - gpuigs only has two arguments.
                     51:  - integ now takes two arguments, like deriv.
                     52:  - setrand, getrand, getstack, gettime, glength return a C long, and not a GEN.
                     53:  - pari_randseed no longer global, use setrand/getrand
                     54:  - gerepile(ltop,lbot,0) no longer returns ltop - lbot
                     55:  - nf[5][7] stored in two element form (was Z-basis) for faster inversion
                     56:  - t_POL and t_POLMOD can be freely mixed as long as main variables are the
                     57:    same (result is the expected POLMOD)
                     58:
