Rational Denominator Value Attribute

TypeConditionally Required (1C)
Value Multiplicity1-n
Value RepresentationUnsigned Long (UL)

The integer denominator of a rational representation of Numeric Value (0040,A30A). Encoded as a non-zero unsigned integer value. The same number of values as Numeric Value (0040,A30A) shall be present.

Required if Rational Numerator Value (0040,A162) is present.
