-log(1+2) * 3% + sin(4 5/6)^7

Edit previous calculations and re-calculate, cut and paste at will. Save your work to a text file (automatic or manual), restore it later.

Compact single-line mode or flexible multi-line mode. Show buttons or hide them. Separately adjustable font and button sizes.

Flexible snap-on screen positioning to your preferred location. Enable/disable always-on-top style. Help file included.

Adjust it to suit your preferences: Change the font. Show or hide calculator buttons used with the mouse; adjust their size as well. Switch the work area to single line mode so that it looks like a plain desk calculator. Stretch the window to any size: shrink it down to a tiny utility window stashed in a corner of your screen, or maximize it in multi-line edit mode for complete editing flexibility. Save the work area contents to a text file. Do this manually or automatically when you exit the program, reload it the same way to continue working where you left off.
