I want to split file contents to an outputfile by comparing real number data present in the last line? For example, the file contains of more 100K lines

Start:/abc/def
.....
End 1.2
Start:/xyz/uvw
.....
End 2.8

I want to print everylines from "Start" to "End" to OUTFILE1 if "End" contains values between 1-1.9; Otherwise print all the lines to OUTFILE2 if "End" contains values between 2-2.9. Likewise, mulitple output files have to be generated.

code here 

foreach $lineIn (@file1_list)

{

   $_ = $lineIn;

        if (/Start:/) 
        { 
        $pattern1 = 1; 
        } 
        elsif(/End\s/) 
        { 
        my @slackno = split /\s+/, $_; 
        $pattern2 = 1; 
        push (@buflines, $_); 
        } 
        if ($pattern1 =~ 1 and $pattern2 =~0) 
        { 
        push (@buflines, $_); 
        } 
        else 
        { 
        $pattern1 = 0; 
        $pattern2 = 0; 
        } 

} 
if ($slackno[3] >= 2.0 and $slackno[3] <= 2.9) 
{ 
foreach ( @buflines ) 
{ 

    print FILE2 $_; 
} 
} 
close(FILE2);
