Hi,
I have a number in Decimal notation. I need to convert it to hexadecimal. For this, I am doing
#!/usr/bin/perl
use strict;
use warnings;

my $decimal_number = "254";
my $hexadecimal_number = sprintf("%x",$decimal_number);

Once I convert decimal number to hexadecimal notation as above, I need to get the Most Significant Bit. That is, if I have a hexadecimal number such as "1110 1111", I need to extract the left most "1" bit and left shift the original hexadecimal number resulting in "1101 1110" as the new value.
Can any monks help me figure out how do I do this in Perl?
Note: Sorry, new to Perl. But so far liking what Perl lets me do for Bio-informatics :)
