in reply to hex to binary

0x11e64 == 73316, but as others have asked, what's the raw byte order you are given and what unpack templates have you tried?

Update: 

c:\@Work\Perl>perl -wMstrict -le
"my $raw = pack 'H*', '641e0100';
 my $le32 = unpack 'V', $raw;
 printf qq{%d decimal  0x%x hex \n}, $le32, $le32;
"
73316 decimal  0x11e64 hex

    The raw bytes out of the file are 641e0100. TBH, i have really no clue right now and have tried the following: 
    perl -le 'print unpack("N", pack("H8",substr("0"x8 . "641e0100",-8)));
perl -le 'print unpack("N", pack("H8",substr("0"x8 . "641e0100",-8)));
+'
perl -le 'print unpack("N", pack("H8",substr("0"x8 . "641e01",-8)));'
perl -e "print hex('641e0100')"
perl -e "print hex('641e01')"
perl -e "print unpack('V',pack 'V', hex('641e01'))"
perl -e "print unpack('V', '0x641e01')"
perl -e "print unpack('N', '0x641e01')"
perl -e "print unpack('n', '0x641e01')"
perl -e "print unpack('h', '0x641e0100')"
perl -e "print unpack('h*', '0x641e0100')"
perl -e "print pack('h*', '0x641e0100')"
