The for-loop comes from C, where it follows the form
which does effectively this:
It's usually used for(var=0; var<10; var++) but any valid expression will do. Most languages with for() loops allow them to be flexible like that, though few languages can cram as many things into one expression as C
In the BASH/KSH adaptation, you can put anything inside each statement that you might put inside a (( )) block, including nothing.
OK, using Corona688's code for SINE we now have Sin(), Cos(), NthRoot() and Sqrt() functions.
The 'e' and 'PI' constants are to 17 decimal places, NthRoot() and Sqrt() to 16 decimal places and Sin() and Cos() to 8 decimal places.
These precisions are good enough for basic mathematical tasks, after all KSH93 was not designed to send a spacecraft to Neptune. <wink>

Note the code is sourced into current ksh shell...
Hope you are all enjoying this exercise in futility... ;oD
