Update math/sollya to version 8.0. Changes from version 7.0 to 8.0: ================================ Changes of syntax and output: * Hexadecimal constants ending on '+' or '-' (e.g., 0x123p-) now provoke a syntax error (as it always should have). * The match construct on error now matches (it used to return error). * In certain cases, procedures could not be applied to an empty set of arguments because a syntax error occurred before. This is now possible. * The meaning and use of infinities and signed zeros in intervals has been changed (see documentation for details). * Input and output of decimal constants is now fully exact in rationalmode. In all other instances, a warning message is now produced when an internal constant gets printed in decimal and a rounding occurs. Critical bug fixes: * Making Sollya compile again with recent versions of fplll (at least on the Linux side). Improvements in internal handling: * Improved performance on manipulation of polynomials. Major bug fixes: * Patched a bug in interval erfc. * Patched a bug preventing match to work on unary minus. Major new functionalities: * The interpolate command allows for polynomial interpolation with and without error (see documentation for details). * The bezout command allows for computation of a gcd along with matching cofactors (see documentation for details). Minor new functionalities: * The externaldata command now allows generic external library symbols to be bound to Sollya objects (see documentation for details). * Improvements on use of the L'Hopital rule for function evaluations. * When started as an interactive tool or as a library, Sollya now binds the executable's 0th argument to the Sollya identifier __program_name. * In situations when the user wishes to provide the minimax with real coefficients to fpminimax, it is now possible to give a list of coefficients instead of the expression of the real minimax (see documentation for details). * The free mathematical variable can now be unbound with the rename command (see documentation for details). * The bind command now allows for procedures with an arbitrary number of arguments (see documentation for details). * The char *sollya_lib_get_help_text(char *topic) function now allows for access to the help text of a certain topic. Others: * In certain circumstances, the printing of a list may have had quadratic complexity in the past. This has been corrected. * If the compiler supports the -flto flag; this option is disabled by default though. To enable LTO compilation, use --enable-lto-compilation. On certain systems the -flto flag is supported by the compiler but LTO compilation fails. In this case, it is recommended not to enable LTO compilation. * dirtyfindzeros used to include in the list of zeros any point where the expression given as input evaluated to NaN. Such points are now included only when there is a real suspicion that it could be a true zero of the expression. * externalprocedure, externalfunction and externaldata entries can have cross-dependencies for their symbols. The tool now makes sure all symbols are unloaded in the precise inverse order of their loading, to allow for such cross-dependencies. * chebyshevform command can now be used out of execute() statements. * remez command now tries to recognize the situation when the optimal error function is identically 0. * configure now allows for cross-compilation. Deprecated functionalities: * Deprecated readxml and printxml. * Deprecated the proof generation feature of the infnorm command. * Deprecated end-elliptic lists ending with a number as a format list in fpminimax. And many bugs fixed.

sollya: Import sollya-7.0 as math/sollya Sollya is a tool environment and a library for safe floating-point code development, particularly targeted at automated implementation of math libraries like libm. Derived from wip/sollya.
