newRPL: all results mode?

[Nigel (UK)]

I like this approach. With a function that finds the minimum and maximum values between the \\ delimiters it could be used for interval arithmetic as well as for its intended purpose.

It might be an idea to combine this approach with the following. Instead of returning \\...\\ directly, operators could return variables representing signs and/or integers as part of an expression. So \\4\\ sqrt would return 2*s1; \\9\\ sqrt would return 3*s2. Adding them would give 2*s1 + 3*s2. Then s1 and s2 could be substituted with lists, \\..\\ structures, or even just 1 or -1, using SUBST or the | operator.

This would also work with inverse trig functions. \\0.5\\ ASIN could return

Code:

\\ 30+360*n1 150+360*n2 \\ instead of just \\ 30 150 \\.

Is this too much complication?
