arrays.index_to_int
arrays.index_to_int(array_of_inputs, index)
说明
以整数形式返回数组中指定索引处的值。
索引是一个整数值，表示数组中元素的位置。
默认情况下，数组的第一个元素的索引为 0，最后一个元素的索引为 n-1，其中 n 是数组的大小。
负索引可用于访问数组中相对于数组末尾的元素。例如，索引 -1 表示数组中的最后一个元素，索引 -2 表示数组中的倒数第二个元素。
形参数据类型
ARRAY_STRINGS|ARRAY_INTS|ARRAY_FLOATS，INT
返回类型
INT
代码示例
示例 1
当索引处的值为非数字字符串时，此函数调用会返回 0。
arrays.index_to_int(["str0", "str1", "str2"], 1) = 0
示例 2
此函数返回索引为 -1 的元素。
arrays.index_to_int(["44", "11", "22", "33"], 0-1) = 33
示例 3
对于越界元素，返回 0。
arrays.index_to_int(["44", "11", "22", "33"], 5) = 0
示例 4
此函数从索引为 1 的浮点数组中提取元素。
arrays.index_to_int([1.100000, 1.200000, 1.300000], 1) = 1
示例 5
此函数从索引 0 处的 int 数组中提取元素。
arrays.index_to_int([1, 2, 3], 0) = 1
