Civil Engr. vers. r.m.03 Notes on JavaScript Calculator - sCal    Operation on lowest level = a simple calculator: click on-screen buttons or use keyboard -- best for inserting values or programming. On a higher level, some functions are available as buttons or from drop-down select menus: designated by x}. These operate directly on entire value in x-display, not just last term, when the [Do] clicked. (The [^] takes all values left of it as base, all to the right as exponent.) Trade values in and out of Memory to control. -Experiment-. Test on known data.    *} Programs invoked with the [JS] button, gives much more control: replace alpha-characters with numeric, or insert after /*com'nt-prompt*/ ) before closing ')'. Write legitimate Java Script expressions --evaluated according to interpreter's parser. NaN is Not a Number, can often correct.    Programming is on the highest level. Definitely view source code. Programming experience is desireable, but with minimal effort, one's most-used functions can be inserted in the source (well commented for the purpose). Copy - Paste from any TEXT file. s} comments can be set to display.    Public Domain. All code user modifiable, responsible. Original: R. Mohaupt, P.E. Feb, 2003. -http://scal-2.sourceforge.net- * More documentation may be created. * Compact display and file size are goals. Most of the visitors who used this tool also used Mathml (27.3%), Spreadsheet (9.1%), Tex (9.1%) Source code of 'sCal' is available at sCal & sCal2.
