lexical_cast and float
Hi! I use this code to control if a sdt::string is a "float" value: string value("3.14"); try { lexical_cast<float>(value); } catch(bad_lexical_cast& ) { cout<<value<<" is not a float number\n"; } I always obtain a bad_lexical_cast exception.

Perhaps, your locale requires comma as fp: "3,14"

But what if one did want to convert from "3.14" instead of "3,14"? How can one specify the customization in this case? Best regards, Asif
