Is there an alternative to atof in C++

  atof, c++

I am finding that atof is limited in the size of a string that it will parse.

Example
float num=atof("49966.73");
cout<<num;

shows 49966.7

num=atof("499966.73");
cout<<num;

shows 499966

I need something that will parse the whole string accurately, to a floating point number, not just the first 6 characters
