Hello Perlmonks,
I cannot seem to solve this simplistic piece of code...
I have 2 files; 1 is a list of numbers e.g. 85.11 etc. The second is a list of names and numbers, tab-delimited.
e.g. John Doe 85.4
John Dear 84.2
etc.
What I wish to do is take each number from file 1 and search against file 2. Anything number in file 2 within plus or minus 0.5 of the number in file 1 will cause the name and number of that match to be printed. For example, grab 85.11, it is within 0.5 of 85.4 and not 84.2 so only print out John Doe etc.
Here is my feeble attempt thus far.

while (<FH1>) {
    @num=<FH1>;}
close FH1;

foreach $num (@num) {
        chomp $num;
while (<FILE2>) {
    @marks = split(/\t/, $_);    
    $x=$marks[0];
    $y=$marks[1];
    
    if ($num - $y < 1) {
        print OUT "$x\n";        
        }
    }
}
