2.5 Output of Scalar Data
To output a scalar, you can use the print and printf built-in
functions. We have already seen examples of the print command, and
the printf command is very close to that in C or C++. Here are a few
examples:
use strict;
my $str = "Howdy, ";
my $name = "Joe.\n";
print $str, $name; # Prints out: Howdy, Joe.<NEWLINE>
my $f = 3e-1;
printf "%2.3f\n", $f; # Prints out: 0.300<NEWLINE>
