Detailed Description

Physical constants (i.e. dimensioned values)

Intended use:

Public interface

Review Status

Reviewed By:
UNKNOWN

Prerequisite

Etymology

A QC is based on the Quantum and C (constants) class

Synopsis

QC:name will produce a Quantity (Quantum<Double>) value consisting of a value and a unit. See the Quantum class for possibilities of manipulating quanta. tQuantum will give a list of the currently available constants

Example

To obtain the velocity of light in pc/a, use:

#include <casacore/casa/Quanta.h>
Double vel_pcpy = (C::c).convert("pc/a").getValue();
casacore::C::c
const Double c
Fundamental physical constants (SI units):
casacore::Double
double Double
Definition: aipstype.h:55

The following constants are defined as public data members of class QC.
