Classes
class	OPTtimers
	Provides a common interface to the different timing routines that are available in different platforms. More...
class	OPTrand
	Provide a common interface to the different random generators that are available in different platforms. More...

Namespaces
namespace	OPTtypes_di_unipi_it
	The namespace OPTtypes_di_unipi_it is defined to hold all the data types, constants, classes and functions defined here.

Macros
#define	OPT_TIMERS   5
	The class OPTtimers is defined below to give an abstract interface to the different timing routines that are used in different platforms.
#define	OPT_RANDOM   1
	The class OPTrand is defined below to give an abstract interface to the different random generators that are used in different platforms.

Functions
template<class T >
void	DfltdSfInpt (istream *iStrm, T &Param, const T Dflt, const char cmntc='#')
	Template function for reading parameters from a istream.

Detailed Description

Small classes are provided for:

• timing of a code;
• generating random numbers;
• extracting "infinity" and "machine epsilon" of numeric types.

The classes can be adapted to different environments (if needed) by setting a compile-time switch in this file.

Additionally, a function is provided for safely reading numbers out of a istream.
