dr_jgbn,
For example, grab 85.11, it is within 0.5 of 85.4

Last time I checked, 85.4 + .5 is 85.9 which is still less than 85.11. I will assume for now that was just a typo.

Since you do not say how large these files are, I will assume memory is no object. Since you do not say if the tab delimited file has more than two fields, I will assume that the name is in the first field and the second field is the number. Finally, I will assume run-time speed is not critical. 

#!/usr/bin/perl
use strict;
use warnings;

open (NUMBERS, '<', "numbers.txt") or die "Unable to open numbers.txt 
+for reading : $!";
open (NAMES, '<', "names.txt") or die "Unable to open names.txt for re
+ading : $!";

my %numbers = map {chomp; $_ => 1} <NUMBERS>;
my %names = map {chomp; split /\t/ , $_ , 2} <NAMES>;

for my $name ( keys %names ) {
    my $names_number = $names{$name};
    for my $number ( keys %numbers ) {
        my $delta = abs $number - $names_number;
        if ( $delta <= .5 ) {
            print "$name : $names_number is within range of $number\n"
+;
            last;
        }
    }
}
