[boost] Convert "60%" to 0.6

I'm using boost::lexical_cast to convert strings to double. However I just 
run into a string with a percent sign where boost::lexical_cast throws 
boost::bad_lexical_cast. As far as I can see there is no way to configure 
boost::lexical_cast to convert eg. "60%" to 0.6. I also checked out 
boost::numeric_cast but from what I read I think it doesn't help either.

Is there anything in Boost which I can use to convert a more descriptive 
string like "60%" to a double?
