Thanks all, in case you are interested -- I ended up using sed:

floatVar1=$(echo $Var1 | sed 's/\([0-9]*\(\.[0-9]*\)\?\)[eE]+\?\(-\?[0-9]*\)/(\1*10^\3)/g;s/^/scale=30;/'| bc)

There are some difficulties with the specific scientific notation my data files were using. (having an extra + after the E, 1.00e+1 = 10), so I had trouble getting bc to work, but I may have just messed up. However, the idea behind the question was supposed to be specifically how to convert something from scientific notation to float. Sorry for the confusion.

xml_set_notation_decl_handler - Set up notation declaration handler

SYNOPSIS
bool xml_set_notation_decl_handler (resource $parser, callable $handler) DESCRIPTION
Sets the notation declaration handler function for the XML parser $parser. A notation declaration is part of the document's DTD and has the following format: <!NOTATION <parameter>name</parameter> { <parameter>systemId</parameter> | <parameter>publicId</parameter>?> PARAMETERS
o $parser - A reference to the XML parser to set up notation declaration handler function. o $handler -$handler is a string containing the name of a function that must exist when xml_parse(3) is called for $parser. The function named by $handler must accept five parameters: handler (resource $parser, string $notation_name, string $base, string $system_id, string $public_id) o $parser - The first parameter, parser, is a reference to the XML parser calling the handler. o $notation_name - This is the notation's $name, as per the notation format described above. o $base - This is the base for resolving the system identifier ($system_id) of the notation declaration. Currently this parameter will always be set to an empty string. o $system_id - System identifier of the external notation declaration. o $public_id - Public identifier of the external notation declaration. If a handler function is set to an empty string, or FALSE, the handler in question is disabled. Note Instead of a function name, an array containing an object reference and a method name can also be supplied. RETURN VALUES
Returns TRUE on success or FALSE on failure. PHP Documentation Group XML_SET_NOTATION_DECL_HANDLER(3)
