[rrd-users] Empty sections in AREA on graph

[Steve Shipway]

This gives me the idea for some new RPN functions in RRDtool --

ROUND -- pops top element from stack, replaces with closest integer (to go
with the existing FLOOR and CEIL)
x,a,b,INRANGE -- push TRUE onto stack if a<=x<=b, FALSE otherwise(or call it
'BETWEEN'?)

Maybe I will brave github again and code them up...

I believe there are a couple conventions to choose from.
What is the closest integer to 5.5 ?
And what is the closest integer to 6.5 ?
Some will say the answer is 6 to both questions, others will say 6 and 7.

You can probably share a lot of code with LIMIT.
