名称
tuple_is_numbertuple_is_numberTupleIsNumberTupleIsNumbertuple_is_number — 检查元组（字符串）是否表示数字。
签名
Herror tuple_is_number(double T, Hlong* IsNumber)
Herror T_tuple_is_number(const Htuple T, Htuple* IsNumber)
def tuple_is_number(t: MaybeSequence[Union[float, int, str]]) -> Sequence[int]
def tuple_is_number_s(t: MaybeSequence[Union[float, int, str]]) -> int
描述
tuple_is_numbertuple_is_numberTupleIsNumberTupleIsNumberTupleIsNumbertuple_is_number checks each element of the input tuple
TTTTtt whether it represents a number. If the element is a
number (real or integer), 1 is returned for that element.
If the element is a string, it is checked whether the string represents a
number. If so, 1 is returned, otherwise 0.
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_numbertuple_is_numberTupleIsNumberTupleIsNumberTupleIsNumbertuple_is_number,
which can be used in an expression in the following syntax:
IsNumber := is_number(T)
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。
