tuple_is_realtuple_is_realTupleIsRealtuple_is_realTupleIsRealTupleIsReal — Test if the internal representation of a tuple is of type real.

tuple_is_realtuple_is_realTupleIsRealtuple_is_realTupleIsRealTupleIsReal tests if the internal representation of the input tuple TTTTTt is of type real. In that case the value 1 (true) is returned in IsRealIsRealIsRealIsRealIsRealisReal, otherwise the value 0 (false) is returned. If a tuple consists of real elements only, IsRealIsRealIsRealIsRealIsRealisReal can nevertheless be 0 in case the internal representation is H_TYPE_MIXED; see tuple_typetuple_typeTupleTypetuple_typeTupleTypeTupleType for details.


Even if all tuple elements are of type real, tuple_is_realtuple_is_realTupleIsRealtuple_is_realTupleIsRealTupleIsReal returns 0 (false) if the internal representation of the tuple is of type H_TYPE_MIXED. To test if the elements of the tuple are of type real the operator tuple_is_real_elemtuple_is_real_elemTupleIsRealElemtuple_is_real_elemTupleIsRealElemTupleIsRealElem should be used.

Is the input tuple of type real?

Example (HDevelop)

tuple_is_real ([3.1416,'pi',3], IsRealA)
* IsRealA = false
tuple_is_real ([1.0,2.0,3.0], IsRealB)
* IsRealB = true
tuple_is_real ([], IsRealC)
* IsRealC = true


If the parameters are valid, the operator tuple_is_realtuple_is_realTupleIsRealtuple_is_realTupleIsRealTupleIsReal returns the value 2 (H_MSG_TRUE).
