RANDARRAY 函数

RANDARRAY函数返回一个随机数数组。

RANDARRAY函数返回一个随机数数组。用户可以指定要填充的行和列的数量,最小值和最大值,以及返回整数或十进制值。 参数 必需 描述 [rows] 否 要返回数据的行数 [columns] 否 要返回数据的列数 [min] 否 随机数的最小值 [max] 否 随机数的最大值 [whole_number] 否 返回整数或浮点数:整数则为true,浮点数为false。 注意: RANDARRAY 函数仅在allowDynamicArray为true时有效。 RANDARRAY 函数将返回一个数组,如果该数组是公式的最终结果,则将溢出。 如果没有行或列参数,RANDARRAY将返回0到1之间的一个值。 如果不提供最小值或最大值参数,则RANDARRAY将分别默认为0和1。 参数最小值必须小于最大值,否则RANDARRAY将返回#VALUE!错误。 如果不输入Whole_number参数,则RANDARRY将默认为FALSE,即浮点数。
