::::(unindent) It's difficult to talk about feasibility abstractly. You could represent var x simply as "root of that function" without fully evaluating it, and later logic may simply eliminate that function, hence the root, altogether, then good, lots of work saved; but if you are forced to take a value at some point, it then all depends on how you are going to use that value: you need to make decision now on precision desired, which can be [[wp:Wilkinson's_polynomial|surprisingly non-trivial]]. Stuff may be theoretically possible, but it's quite different from being practical, alas. --[[User:Ledrug|Ledrug]] 16:40, 28 June 2011 (UTC)
::::::: In the REXX examples, when using more decimal digits of ''pi'' and ''e'', I found the limit of decimal precision is simply determined by how many digits are specified (via '''numeric digits nnn'''). Of course, this slows up computation. -- [[User:Gerard Schildberger|Gerard Schildberger]] ([[User talk:Gerard Schildberger|talk]]) 04:55, 24 August 2018 (UTC)
