Library: Util
Package: Units
Header: Poco/Util/Units.h
Description
A Value with a unit.
- V is the type you are storing
- U is the unit of the Value
This class is usually not used directly; client code should use the typedef'd instantiations defined in the Values and Constants namespace.
Example:
using namespace Poco::Util::Units::Values;
std::cout << "One mile is " << km(mile(1)) << std::endl;
// Output: One mile is 1.60934 km
std::cout << "Flow rate is " << m3(mile(1)*inch(80)*foot(9))/s(minute(5));
// Output: Flow rate is 29.9026 (m)^3.(s)^-1
hours h;
h = cm(3); // Compile-time error: incompatible units
h = 4; // Compile-time error: 4 of what?
h = days(4); // Ok: h is 96 hours
