  s<-c(1101111,112321)
# [A]
  s/(10^(floor(log10(s))-2))
  # [1] 110.1111 112.3210

# [B]
  sub("([0-9]{3})","\\1.",as.character(s))
  [1] "110.1111" "112.321"

# [C]
  as.double(sub("([0-9]{3})","\\1.",as.character(s)))
  # [1] 110.1111 112.3210

Not sure exactly what you are asking; but these should give some ideas.
