Yes...

#declare i = 1.234;
#debug concat("i = ", str(i, 0, -1), "\n")
For a vector you could use a macro like this:
#macro VectorString(P, Precision)
concat("<",
str(P.x, 0, Precision),
", ",
str(P.y, 0, Precision),
", ",
str(P.z, 0, Precision),
">")
#end
...
#declare V = <1,2,3>
#debug concat("V = ", VectorString(V, -1), "\n")
See "String Functions" and "Text Message Streams" of the POV-Ray
documentation.

Yes it can, but...

It's only calculated when the #declare is parsed.
When you invoke the #declared value, it is not parsed
again. You'ld have to use a #macro for that.
