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.
