描述

tuple_lesstuple_lessTupleLessTupleLessTupleLesstuple_less tests whether the input tuple T1T1T1T1t1t1 is less than T2T2T2T2t2t2. A tuple T1T1T1T1t1t1 is said to be less than a tuple T2T2T2T2t2t2, if T1T1T1T1t1t1 has been found to be less when comparing it elementwise to T2T2T2T2t2t2 or if the first min(|T1|,|T2|) elements are equal and T1T1T1T1t1t1 has got less elements than T2T2T2T2t2t2。

With the elementwise comparison, the elements of T1T1T1T1t1t1 and T2T2T2T2t2t2 are compared one by one. If the two elements are equal, the next pair of elements will be examined. If the element of T1T1T1T1t1t1 is less than that from T2T2T2T2t2t2, the result is 1 and the comparison will be aborted. If the element of T1T1T1T1t1t1 is greater than that from T2T2T2T2t2t2, the result is 0 and the comparison will be aborted. If all elements have been tested and if all were equal, the result is 0.

As a precondition for comparing the tuples elementwise two corresponding elements must either both be (integer or floating point) numbers or both be strings. Otherwise tuple_lesstuple_lessTupleLessTupleLessTupleLesstuple_less returns an error.

例外：空输入元组

若一个输入元组为空而另一个不为空，则空元组被视为小于非空元组。

HDevelop 内联操作

HDevelop 为 tuple_lesstuple_lessTupleLessTupleLessTupleLesstuple_less 提供了内联操作，可在表达式中使用，语法如下：

Less := T1 < T2

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。
