Hmmm. Have you considered passing a "sqrt" function to the contructor
hash
###############################
use Math::Complex; # allow for negative numbers
$tt2->process("mytemplate",
{
sqrt => sub { sqrt($_[0]) },
});
###############################
Alternativly, you could create a "Maths" plugin that created maths
operators
##########################
package Template::Plugin::Maths;
use base qw(Template::Plugin);
use Math::Complex;
sub sqr
{
my $self = shift;
my $x = shift;
return sqrt($x)
}
1;
######################
[% USE Maths %]
The square root of -4 is [% Maths.sqr(-4) %]
######################
Hope this helps.
As for uniary minus, I suggest you create a "neg" operator that returns
the negative of that number
