Dependencies:

• c++11 >=
• gcc
• Boost 1.57 >=

EIRational (Extended Infinity Rational):

Is an extension of boost_rational<int> that allows using infinity.

NDTime (Natural Deep Time):

Allows to work with the international standar time format hh:mm:ss:mmss and it also allows to work with smaller time units as:

• microseconds
• nanoseconds
• picoseconds
• femtoseconds

This time units are the smaller mesurable units in phisics

Available constructors

1 - NDTime();
2 - NDTime(const NDTime& val);
3 - NDTime(std::initializer_list<int> val);
4 - NDTime(const string val);

1 Default constructor: Initialize a new NDTime with value zero as default.
2 Copy constructor: Initialize a new NDTime with the exact same value as the first parameter val.
3 Natural constructor: Initialize a new NDTime with values from {hours} to {hours, ..., femtoseconds}.
11 Parser constructor: Intializa a new NDTime parsing a string val. accepted strings are: {"inf","-inf",["hh", ..., "hh:mm:ss:mmss:mcs:nnss:ppss:ffss"]} the last format is the international standar time format extended until femtoseconds.

Available operators

Operator	Left type	Right type
+=	NDTime	NDTime
-=	NDtime	NDTim
+	NDTime	NDTime
-	NDTime	NDTime
==	NDTime	NDTime
!=	NDTime	NDTime
<	NDTime	NDTime
>	NDTime	NDTime
<=	NDTime	NDTime
>=	NDTime	NDTime
<<	std::ostream	NDTime
>>	std::istream	NDTime

Available methods

void resetToZero();

// Resets the NDTime object to zero (i.e. 00:00:00:000:000:000:000:000)

static methods

static void startDeepView();

// When deep view mode is enabled calling NDTime::startDeepView() the << operator start printing all the units from hours to femtoseconds.

// line:
std::cout << NDTime({1,1,1,1,1,1,1,1}) << std::endl;
NDTime::startDeepView();
std::cout << NDTime({1,1,1,1,1,1,1,1}) << std::endl;

// output:
01:01:01:001
01:01:01:001:001:001:001:001

static void stopDeepView();

Stops deep view mode calling NDTime::stopDeepView()

// line:
NDTime::startDeepView();
std::cout << NDTime({1,1,1,1,1,1,1,1}) << std::endl;
NDTime::stopDeepView();
std::cout << NDTime({1,1,1,1,1,1,1,1}) << std::endl;

// output:
01:01:01:001:001:001:001:001
01:01:01:001

static NDTime infinity();

returns a NDTime with value possitive infinity

static NDTime minus_infinity();

returns a NDTime with value negative infinity
