函数参考

Mod

求模运算.

Mod ( 数值1, 数值2 )

参数

数值1 被除数.
数值2 除数.

返回值

成功: 返回 数值1 除以 数值2 后的余数.
失败: 返回 -1,说明除数为零.

注意/说明

This function guarantes that dividend = Int(dividend / divisor) * divisor + Mod(dividend, divisor).

This function does not guarantee that dividend or divisor can be represented accurately, specifically with floating point numbers.

If integers are passed this function does an integral modulo operation. Otherwise it falls back to a floating point operation which per the previous remark means it may not produce the expected output.

示例/演示


Local $n = 18
If Mod($n, 2) = 0 Then
    MsgBox(0, "", $n & " is an even number.")
Else
    MsgBox(0, "", $n & " is an odd number.")
EndIf

Local $x = Mod(4, 7) ;$x == 4 because the divisor > dividend

Local $y = Mod(1, 3 / 4) ;$y == 0.25 because the divisor is a float
