dec2bin.m: Fix algorithm for numbers less than intmin ('int32') (bug #58147).
* dec2bin.m: Document that negative numbers are restricted to < -flintmax/2.
Validate input and error if negative numbers greater than -flintmax/2 are
present. Update BIST tests.

Summary of important user-visible changes for version 7 (yyyy-mm-dd): ---------------------------------------------------------------------- ### General improvements - Many functions in Octave can be called in a command form---no parentheses for invocation and no return argument assignment---or in a functional form---parentheses and '=' for assignment of return values. Command Form Example `mkdir new_directory` Function Form Example `status = mkdir ("new_directory")` Octave now handles errors that occur in a consistent manner. If called in command form and there is a failure, an error is thrown and a message printed. If called in functional form, no error or message is printed and the failure is communicated to the programmer via the output status variable. The following list of functions have been modified. * `copyfile` * `fcntl` * `fileattrib` * `kill` * `link` * `mkfifo` * `movefile` * `rename` * `rmdir` * `symlink` * `unlink` ### Graphics backend - Support for Qt4 for graphics and the GUI has been removed. ### Matlab compatibility - The function `griddata` now implements the "v4" Biharmonic Spline Interpolation method. In adddition, the function now accepts 3-D inputs by passing the data to `griddata3`. - Coordinate transformation functions `cart2sph`, `sph2cart`, `cart2pol`, and `pol2cart` can now accept either row or column vectors for coordinate inputs. A single coordinate matrix with one variable per column can still be used as function input, but a single output variable will now contain just the first output coordinate, and will no longer return the full output coordinate matrix. Output size matches the size of input vectors, or in the case of an input matrix will be column vectors with rows corresponding to the input coordinate matrix. ### Alphabetical list of new functions added in Octave 7 * `endsWith` * `rng` * `startsWith` ### Deprecated functions and properties The following functions and properties have been deprecated in Octave 7 and will be removed from Octave 9 (or whatever version is the second major release after 7): - Functions Function | Replacement -----------------------|------------------ | - Properties Object | Property | Value -----------------|---------------|------------ | | ### Removed functions and properties The following functions and properties were deprecated in Octave 5 and have been removed from Octave 7. - Functions Function | Replacement -------------------------|------------------ `output_max_field_width` | `output_precision` `is_keyword` | `iskeyword` - Properties Object | Property | Value -----------------|---------------|------------ `text` | `fontangle` | `"oblique"` `uibuttongroup` | `fontangle` | `"oblique"` `uicontrol` | `fontangle` | `"oblique"` `uipanel` | `fontangle` | `"oblique"` `uitable` | `fontangle` | `"oblique"` ### Old release news - [Octave 6.x](etc/NEWS.6) - [Octave 5.x](etc/NEWS.5) - [Octave 4.x](etc/NEWS.4) - [Octave 3.x](etc/NEWS.3) - [Octave 2.x](etc/NEWS.2) - [Octave 1.x](etc/NEWS.1)
