Version History

I started this history with Euler 1.50. Note that the version numbers are inconsistent with the OS/2 version, which is no longer maintained.

1.73

Fixed a strange bug in the Windows version of Euler (related to breaks in castled loops).

1.71

Fixed a bug in shuffle.

 

Euler can now call an external editor, which can be chosen in a separater dialog.

1.70

Fixed a bug in copying, saving and printing, which caused the current window to become empty.

 

Wrote a notebook for boundary value problems, and a file to test a Newton barrier method.

1.69

Fixed a bug in bitmap output, when the size is not the window size. Background was not deleted.

1.68

Improved the demos and the help command.

 

Utility files were missing in 1.67.

1.67

Fixed a bug from version 1.61 in copying and printing (thanks to Werner Heid).

 

Some changes in the 3D functions to improve usability. New functions are f3d, f3daxis, f3dpolar, f3daxispolar.

 

Utility files (loaded from euler.cfg at Euler start) are now in a subdirectory progs/util to avoid accidental changes.

1.66

Improved the wait function. It does no longer check keys for times less than 1 sec, but simply sleeps. This removes a bug in animations.

1.65

User plots now map to functions.

 

Bug in animation demo under Windows XP removed.

1.64

Fixed a bug in normal(), which is due to a compiler bug in Visual C++.

 

The internal editor is now larger and works differently. Loaded or saved file names are remembered and used instead of the default $$$$.e.

1.63

Font for the internal editor is now the same as the text window font.

1.62

Euler is now compiled using Visual C++.

1.61

Improved key presses to stop animations.

  Use coprocessor interrupts to detect floating point errors. This should be faster.
  Graphics now clip to the drawing area. New functions are clip and unclip.

1.60

Improved animations.

  Worked on the documentation.

1.59

New Version for Linux

Reworked the documentation, examples and overview.

1.56

Removed triangles (now default)

1.55

Fixed an error with the file name, when saving the internal editor file

Wrote shiftleft, shiftright, rotleft and rotright

1.54

Global strings can now be changed, when the lenght is shorter

End key now prints "endfunction" only on empty line in function editor

1.53
