I have one reference file 1.txt with 2 columns and I want to search other 10 files (a.txt, b.txt......h.txt each with 5 columns) corresponding to the values of 2nd column from 1.txt. If the value from 2nd column from 1.txt matches with the value of 4th column of 10 files, then print the row as well as file name.
Also, in 1.txt for eg. 1st value is -191.632 but originally in a.txt it is -191.6318, so I also want to print values same upto two decimal places and rest places can be any number.

1.txt:

1.35732 -191.632
1.36229 -190.8716
1.35503 -191.3254
1.35597 -191.2652

a.txt:

271640.000 0.49000 -0.0000036574 -191.6318 -183.82380
271650.000 0.49155 0.0000033909 -198.30111 -198.73140
271660.000 0.48775 0.0000014657 -191.3254 -199.84910
271670.000 0.48212 -0.0000004152 -195.48446 -193.15580

Please guide.
Thanks
I'm not sure if you want the values in 1.txt column 2 and a-h.txt column 4 truncated to two decimal places or rounded to two decimal places (with your sample input, the results are the same) and I'm not sure why DGPickett thinks join and sort would be easier than awk, but here are ways to use awk to do what I think you're requesting...
Code:
echo "awk with rounded values"
awk ' FNR == NR {v[sprintf("%.2f", $2)]}
sprintf("%.2f", $4) in v {print $0, FILENAME}' 1.txt [a-h].txt

echo "awk with truncated values"
awk '
function trunc(val) {
        split(val, a, /[.]/)
        return a[1] "." substr(a[2] "00", 1, 2)
}
FNR == NR {v[trunc($2)]}
trunc($4) in v {print $0, FILENAME}' 1.txt [a-h].txt

DESCRIPTION

       This manual page documents briefly the pescetti command.

       Here are a list of the available options and what they do. You must specify exactly one from --demo, --generate or --load.

       --help	 Prints the help text

       --demo	 Demonstration mode. Generates one hand with permutations and the tutorial for how to use them.

       --generate=N
		 Generate N random boards

       --load=boards.txt
		 Load boards+analysis from boards.txt

       --load-dds=boards.dds
		 Load boards from boards.dds in dds format

       --load-analysis=tricks.txt
		 Load analysis from tricks.txt

       --permutations=permutations.txt
		 Generate the permutations and save them to the given file

       --curtains=curtains.txt
		 Save curtain cards to file curtains.txt

       --save=boards.txt

       --stats	 Generate statistics about the set of boards; included in the hands output

       --analyze Run the dds analyzer on the boards and print the resulting numberof tricks (warning SLOW)

       --criteria=
		 A  list of criteria to apply to each generated hand to generate specific hand types.  The list should be space separated and each
		 item may be suffixed with a colon and a (fractional) probability value which can be used to weight the criteria.

		 E.g. --criteria="weaknt:0.8 strongnt:0.5"

		 Valid criteria are: unbalanced weaknt strongnt twont strongtwo weaktwo three twoclubs 4441  singlesuit  twosuits  partscore  game
		 slam game-invite slam-invite jumpshift jumpfit splinter bacon weird

       --probability=factor
		 Generate  hands matching the criteria with only the given probability. Factor is in the range 0 to 1. On each attempt to generate
		 a board it is rejected if it doesn't match the criteria with the given probability.  A factor of about  0.8  gives  roughly  half
		 matching boards
