Re: how to remove the letter n from a line of text

Let me be more clear and correct myself:
What I was actually trying was this:

$my_variable =~ s/n/e-9/;

where the variable $my_variable has this in it: 3.5n


and I was hoping to change it to:

3.5e-9


when I read-in the data and do the following (below) on $_

s/n/e-9/;

it works!

But if I do it like this:

$my_variable =~ s/n/e-9/;

The n is removed but not replaced by the e-9

Again, I cannot reproduce your problem based on your verbal description:

C:\tmp>type t.pl
use warnings; use strict;
my $my_variable = '3.5n';
$my_variable =~ s/n/e-9/;
print $my_variable;

C:\tmp>t.pl
3.5e-9

Is there a specific reason why you don't post a minimal self-contained
script that produces your problem as recommended in the posting guidelines?
