Hello,
I am seeing this behavious with boost::lexical_cast<std::string>(double)
occasionaly numbers like 76.32 are being converted to strings of the
form 76.319999999
The expected behavior is seen for almost all doubles except for a few
which are reproducible
e.g. 76.32..

here is a simple program,
int main() {
double  d=76.32;
std::string s = boost::lexical_cast<std::string>(d);
cout << s << endl;
}

output
76.319999999...

a) am i doing something wrong ??
b) if this is not wrong s this standard behavior ??

Thanks
Digz
