String concatenation in Perl 5?

Question

Perl

print "1fred2" * 2."\n";
Why is it not interpreted?
Here's what's in the console:

String found where operator expected at hello.pl line 1, near "2."\n""
(Missing operator before "\n"?)
syntax error at hello.pl line 1, near "2."\n""
Execution of hello.pl aborted due to compilation errors.

Shouldn't 1 be multiplied by 2 and then converted to a string due to the concatenation operator (i.e. 2 would have to be converted to "2")?

Answer 1

Put a space after 2. Otherwise "." treated as a number instead of a concatenation.
