Herror tuple_is_real_elem(double T, Hlong* IsReal)
Herror T_tuple_is_real_elem(const Htuple T, Htuple* IsReal)
def tuple_is_real_elem(t: HTupleType) -> Sequence[int]

描述
tuple_is_real_elemtuple_is_real_elemTupleIsRealElemTupleIsRealElemTupleIsRealElemtuple_is_real_elem tests the elements of the input tuple TTTTtt
separately.
For all elements of type real the value 1 (true) is returned in
IsRealIsRealIsRealIsRealisRealis_real, else 0 (false) is returned.
例外：空输入元组
If the input tuple is empty, the operator returns an empty tuple.
HDevelop 内联操作
HDevelop provides an in-line operation for tuple_is_real_elemtuple_is_real_elemTupleIsRealElemTupleIsRealElemTupleIsRealElemtuple_is_real_elem,
which can be used in an expression in the following syntax:
IsReal := is_real_elem(T)
注意
tuple_is_real_elemtuple_is_real_elemTupleIsRealElemTupleIsRealElemTupleIsRealElemtuple_is_real_elem returns 2 (
H_MSG_TRUE)
if the internal data type
of the elements of the tuple is real. In contrast to
tuple_is_numbertuple_is_numberTupleIsNumberTupleIsNumberTupleIsNumbertuple_is_number it does not return whether the elements of a tuple
could be represented as real values.
执行信息
- 多线程类型：独立（即使使用独占算子也能并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。
参数
TTTTtt (输入控制) tuple(-array) → HTupleHTupleTypeHTupleHtuple (real / integer / string / handle) (double / int / long / string / HHandle) (double / Hlong / HString / HHandle) (double / Hlong / char* / handle)
Input tuple.
IsRealIsRealIsRealIsRealisRealis_real (输出控制) number(-array) → HTupleSequence[int]HTupleHtuple (integer) (int / long) (Hlong) (Hlong)
Are the elements of the input tuple of type real?
示例（HDevelop）
tuple_is_real_elem ([3.1416,'pi',3,3.0], IsReal)
* IsReal = [true, false, false, true]
结果
如果参数有效，算子
tuple_is_real_elemtuple_is_real_elemTupleIsRealElemTupleIsRealElemTupleIsRealElemtuple_is_real_elem 返回值 2 ( H_MSG_TRUE )。
