Is there an (easy) way to give the interval representation of a (rational)
number, i.e. without typing N[rational_number, 50] or something like that,
i.e. [round-to-min-infinity(rational_number), round-to-plus-infinity(number)]?
There is a function Interval[], but it's not specified how the end-points
of the interval are defined...
Do there exist functions
round-to-minus-infinity
-plus-infinity
-to-zero
-to-nearest
