I'm not sure but I think you're trying to find out if the result of the divide is a whole number. You can use modulus operator % to get the remainder from the divide operation.
我不确定，但我想你们是想知道除以的结果是不是一个整数。您可以使用模数运算符%从除运算中获得余数。
Assuming i and split are integer types (int, long, short, etc), then modulus returns 0 when i or split is an integer value, ie:
假设i和split是整数类型(int, long, short等)，那么当i或split为整数时，模数返回0，即:
if ( i % split == 0 ) {...}
