that doesn't actually exist in the standard number system; there is no single real number that's immediately next to 0, you can always get closer. some number systems have infinitesimals, but real numbers don't. and any very small real number with a terminating decimal expression is simply the inverse of a very large number, which is simply a long string of 1+1+1+1+1...

2+1 .. . ... 3
