* ext/bcmath: coding style: use indentation And add braces to block statements, as the current code was pretty much unreadable with how inconsistent it was. * ext/bcmath: Remove some useless header inclusions * ext/bcmath: Use standard C99 bool type instead of char * ext/bcmath: Include specific headers instead of config.h * Restructure definitions to reduce header inclusions * Use size_t as a more appropriate type * Remove unused variable full_scale * Refactor bc_raisemod() to get rid of Zend dependencies This separates the concerns of throwing exceptions back into the PHP_FUNCTION instead of being the responsibility of the library * Refactor bc_raise() to get rid of Zend dependencies This separates the concerns of throwing exceptions back into the PHP_FUNCTION instead of being the responsibility of the library * Refactor bc_divmod() and bc_modulo() to return bool Return false on division by 0 attempt instead of -1 and true on success instead of 0 * Refactor bc_divide() to return bool Return false on division by 0 attempt instead of -1 and true on success instead of 0
