Etymology
From Measure, Value and Double
Synopsis
An MVDouble is a simple Double, to be used in simple, single value Measures. Requirements can be found in the MeasValue base class.
The only reasonable constructor is (but all MeasValue constructors are present) MVDouble(Double); and an operator Double takes care of all other possibilities. Its external use is for MeasConvert, to distinguish between input in internal Measure units, and values which have to have units applied.
Example
See e.g. MFrequency
Motivation
To aid coordinate transformations possibilities

◆ getVector()
Adjust value: taken from base class, a NOP.
Get the value in internal units
Implements casacore::MeasValue.
◆ near()
◆ nearAbs()
◆ operator Double()
| casacore::MVDouble::operator Double | ( | ) | const |
Conversion operator.
◆ operator!=()
◆ operator+=()
◆ operator-=()
◆ operator=()
◆ operator==()
◆ print()
|
virtual |
Print data.
Implements casacore::MeasValue.
◆ putValue()
Set the internal value if correct values and dimensions.
Implements casacore::MeasValue.
◆ putVector()
Set the value from internal units (set 0 for empty vector)
Implements casacore::MeasValue.
