Subject: [boost] [xpressive] capture float?

I'm trying to capture a float with xpressive and put it into a local map.
As a simplified example, I tried just pushing the matched pattern to a
float and the result is always a float containing '0'.
namespace xpr = boost::xpressive;
std::map<float, std::string> l_floatOperMap;
xpr::sregex l_relation = xpr::as_xpr("<=") | ">=" | "<" | ">");
!(xpr::s1 = l_relation) >> (xpr::s2 = (+xpr::_d >> '.' >> +xpr::_d))
However, when I go to print the contents of l_floatOperMap, it contains
only the tuple (0, ""). Is it something I'm doing wrong? It seems like
this should work to me.
