Detailed Description

template<typename T>
class Rulbus::IoFormat< T >

IoFormat together with BoundIoFormat form a class of manipulators for working with streams.

These classes are based on Bjarne Stroustrup's The C++ Programming Language 3rd Ed. Special Edition, p.635, User-Defined Manipulators [2000].

Here is an example of its use.

   Rulbus::IoFormat<double> sci;
   Rulbus::IoFormat<double> alt;

   sci.scientific().width(12).precision(3);
   alt.showplus().width(12).right().fill('#');

   double d = 1234.5678;

   std::cout << d << "  '" << sci(d) << "'" << "  '" << alt(d) << "'" << std::endl;
   

This produces the following output.

   1234.57  '   1.235e+03'  '+####1234.57'
