That is because only integer expressions can be use in test statements in any shell other than ksh93. Did you try earlier this suggestion?
Code:
if [ ${var2%%.*} -gt 6 ]; then

Code:
$ echo $var2
6.1
$ echo ${var2%%.*}
6

Otherwise you could use the utility bc ..

html::parse

HTML::Parse(3)						User Contributed Perl Documentation					    HTML::Parse(3)

NAME

       HTML::Parse - Deprecated, a wrapper around HTML::TreeBuilder

SYNOPSIS

	 See the documentation for HTML::TreeBuilder

DESCRIPTION

       Disclaimer: This module is provided only for backwards compatibility with earlier versions of this library.  New code should not use this
       module, and should really use the HTML::Parser and HTML::TreeBuilder modules directly, instead.

       The "HTML::Parse" module provides functions to parse HTML documents.  There are two functions exported by this module:

       parse_html($html) or parse_html($html, $obj)
	   This function is really just a synonym for $obj->parse($html) and $obj is assumed to be a subclass of "HTML::Parser".  Refer to
	   HTML::Parser for more documentation.

	   If $obj is not specified, the $obj will default to an internally created new "HTML::TreeBuilder" object configured with
	   strict_comment() turned on.	That class implements a parser that builds (and is) a HTML syntax tree with HTML::Element objects as
	   nodes.

	   The return value from parse_html() is $obj.

       parse_htmlfile($file, [$obj])
	   Same as parse_html(), but pulls the HTML to parse, from the named file.

	   Returns "undef" if the file could not be opened, or $obj otherwise.

       When a "HTML::TreeBuilder" object is created, the following variables control how parsing takes place:

       $HTML::Parse::IMPLICIT_TAGS
	   Setting this variable to true will instruct the parser to try to deduce implicit elements and implicit end tags.  If this variable is
	   false you get a parse tree that just reflects the text as it stands.  Might be useful for quick & dirty parsing.  Default is true.

	   Implicit elements have the implicit() attribute set.

       $HTML::Parse::IGNORE_UNKNOWN
	   This variable contols whether unknow tags should be represented as elements in the parse tree.  Default is true.

       $HTML::Parse::IGNORE_TEXT
	   Do not represent the text content of elements.  This saves space if all you want is to examine the structure of the document.  Default
	   is false.

       $HTML::Parse::WARN
	   Call warn() with an apropriate message for syntax errors.  Default is false.

REMEMBER!
       HTML::TreeBuilder objects should be explicitly destroyed when you're finished with them.  See HTML::TreeBuilder.
