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