I am assuming you are using bash or perhaps a POSIX shell like dash.
Your error is telling you that it is not possible to do such a task as these shells have INTEGER arithmetic only.
If you need floating/fixed point arithmetic then you will have to do workarounds using, bc, dc, python, perl, awk or any other methods that are capable of such mechanisms.
(Just an observation, you have both, ${barr1[$i]} and also ${harr1[j]} are these correct?)
EDIT:
Note the second one should have ${harr1[$j]}

syntax(3) User Contributed Perl Documentation syntax(3)NAME
syntax - Activate syntax extensions
VERSION
version 0.004
SYNOPSIS
# either
use syntax 'foo';
# or
use syntax foo => { ... };
# or
use syntax qw( foo bar ), baz => { ... };
DESCRIPTION
This module activates community provided syntax extensions to Perl. You pass it a feature name, and optionally a scalar with arguments, and
the dispatching system will load and install the extension in your package.
The import arguments are parsed with Data::OptList. There are no standardised options. Please consult the documentation for the specific
syntax feature to find out about possible configuration options.
The passed in feature names are simply transformed: "function" becomes Syntax::Feature::Function and "foo_bar" would become
"Syntax::Feature::FooBar".
METHODS
import
syntax->import( @spec );
This method will dispatch the syntax extension setup to the specified feature handlers for the calling package.
import_into
syntax->import_into( $into, @spec );
Same as "import", but performs the setup in $into instead of the calling package.
unimport
syntax->unimport( @features );
This method will trigger uninstallations of the @features from the calling package.
unimport_from
syntax->unimport_from( $from, @features );
Same as "unimport", but will uninstall the @features from $from.
RECOMMENDED FEATURES
o Syntax::Feature::Function
Activates functions with parameter signatures.

Syntax::Feature::Function, Devel::Declare
