Not sure if this is exactly what you want, as in your question the nuber of trailing zeroes changes from i/p to o/p, but, something like:

> cat infile
10000.0000
20000.00

> awk '{printf("%f\n",$1+NR)}' infile
10001.000000
20002.000000

or

> awk '{printf("%.3f\n",$1+NR)}' infile
10001.000
20002.000

Should get you heading in the right direction and give you something to play about with and get to your liking..

How about ...:

#!/bin/bash

LC=1
while read DV
do
  LV=$( echo $DV | cut -d '.' -f 1 )
  RV=$( echo $DV | cut -d '.' -f 2 )
  LV=$(( $LV + $LC ))
  OV=${LV}.${RV}
  echo "$OV" >> out.file
  LC=$(( $LC + 1 ))
done < in.file
cat out.file

exit 0
# finis

[house@leonov] cat in.file
10000.0000
20000.00
[house@leonov] bash test.bash
10001.0000
20002.00
