I have two tab separated files as following
File 1:
35.152000 -1853.494656 0.000000 13.211222
15.978182 0.000000 0.001175 0.000012

File 2:
35.152001 -1853.494657 0.000000 13.211222
15.978182 0.000000 0.001175 0.000011

In the above two files some numbers differ because of change in last digit after decimal. What would be a good routine ignoring differences of +/-1 in the last digit after decimal, so that the result of comparison (of File 1 and File2) shall be equal.
