Hello Andrey,
Have you thought about using the a<b<c and a>b>c to behave like in Mathcad (gives "true" if b is inside the interval (a,c))? I do not mind the way it is in SMath, but I know from my experience as a teacher that this is a standard mistake many students make.

Code:I'm a bit wary of notations that cannot be parsed. a>b>c is an ambigous statement to me, I could parse it as (a>b)>c or perversely a>(b>c), neither of which reflect the intended meaning of (a>b)*(b>c)

I agree that this is a bit questionable. I am not quite sure why Mathcad used it (or most likely - I forgot why) Regards, Radovan |
