You can use the modulo operator %:

您可以使用模运算符%:

numberTwo % numberOne== 0

The modulo finds the remainder of an integer division between 2 numbers, so for example:

模数在2个数字之间找到整数除法的余数,例如:

20 / 3 = 6
20 % 3 = 20 - 6 * 3 = 2

The result of 20/3 is 6.666667 - the dividend (20) minus the integer part of that division multiplied by the divisor (3 * 6) is the modulo (20 - 6 * 3) , equal to 2 in this case.

20/3的结果是6.666667 - 被除数(20)减去该除数的整数部分乘以除数(3 * 6)是模数(20 - 6 * 3),在这种情况下等于2。

If the modulo is zero, then the dividend is a multiple of the divisor

如果模数为零,则除数是除数的倍数

You can use truncatingRemainder. E.g.,

您可以使用truncatingRemainder。例如。,

if number.truncatingRemainder(dividingBy: 10) == 0 {                
    print("number is divisible by 10")   
}
