I am studying with Introduction to the use of SMath Studio Prepared by Gilberto E. Urroz, May 2010.

I don't understand something in ranges and would like some explanation.

Example1 is a definition error, and I'm curious how increment is defined in examples 2-4.

By far obsolete for productive maths.
Think in term of ranging pi 0..0.1,pi ,,,
No matter how small ► can't never exactly end pi.

range() function has two sub functions.
One is with two, other with three parameters.

range() with two parameters has step 1 or -1.
It depends on whether a less or greater than b.

range() with three parameters is relation of start, stop and added.
added is equal to start+step. step can be negative or positive.
When added is greater than start, range will increase.
If added is less than start, range will decrease.

I hope picture below helps to clarify.
