I wouldn't lie by saying that I'm a vivid user of the calculator from the withing the Input Editor/Command file. But at times when the Window's calculator crashes, Staad's calculator comes to the rescue.

hoping to add a few suggestions:

1. rather than using the mouse, entering the values via the numeric pad is much faster; but in such case I'm unable to enter a decimal value as the 'point' button doesn't seem to be mapped with the 'point/period' button with my keyboard. (it does seem to work when I used the number pad section on an external/USB keyboard)

2. and including bracket/parenthesis function would help with computing sequential/continuous values.

3. also the moment we press the enter key / equals to button, the history (or) the keyed in values disappear. Can we have a history or a log to track the earlier entries.... or even the values can stay even after the enter/= is pressed, and they can disappear once the user has made a new entry...

that being said.... also kindly advise, if this calculator (or) the unit converter is accessed from the installed folder without opening/executing the STAAD application, would my usage be logged against the license or these applications are like free to use... 🤔
