Example

// assumes `message` is a DICOM message model object

// Retrieve a backslash-delimited string of floats
// for a specific DICOM tag
var dicomFloats = message.getDICOMFloats("0010,0030");

// Retrieve the values for a specific instance of the tag
// (useful when the tag appears multiple times, e.g. in sequences)
var dicomFloatsInstance = message.getDICOMFloats(
    "0010,0030",
    2 // instance (1 = first instance)
);

// Result:
// - Returned value is a String
// - Floats are delimited by backslashes (e.g. "1.2\\3.4\\5.6")
