You mean the input for the subroutine ? right ?

Is that what you need help with? 

#!/usr/bin/perl --
use strict; use warnings;
use Carp::Always;
my $curWidth = my $curLength = 1;
my $blah  = q{-0.137 + (0.00479 / (W/0.9)) + (2.5593 * (W/0.9 ) ,0.045
+,0 };
print EvalPolynominal( $blah );


sub EvalPolynominal {
    #first parameter gives the polynominal string
    #second parameter gives the min-des width
    #third parameter gives the short-line length
    
    my $polynominal = shift;
    my $curWidth    = shift;
    my $curLength   = shift;
    
    $polynominal =~ s/W/$curWidth/g ;#replace W with current value of 
+min width
    $polynominal =~ s/L/$curLength/g ;#replace L with current value of
+ min Length
    return eval ($polynominal);
}
__END__
Use of uninitialized value $curWidth in substitution (s///) at blah li

eval is for perl code, not math

build a calculator with marpa dsl or use Math::GSL::Poly but don't use eval
