What is the smallest positive integer whose reciprocal contains all 10 digits in the ten consecutive digits starting with the first nonzero digit?

a) smallest when truncated (whether rounding gives same result or not)
b) smallest when rounded (whether truncation gives same result or not)
c) smallest when truncation and rounding give the same result

Note: some algorithms round numbers with a fractional part of exactly 0.5 to the nearest even integer, but for this exercise, 0.5 is always rounded up.
