/= Operator (C# Reference)
The division assignment operator.
Remarks
An expression using the /= assignment operator, such as
x /= y
is equivalent to
x = x / y
except that x is only evaluated once. The / operator is predefined for numeric types to perform division.
The /= operator cannot be overloaded directly, but user-defined types can overload the / operator (see operator). On all compound assignment operators, overloading the binary operator implicitly overloads the equivalent compound assignment.
Example
// cs_operator_division_assignment.cs
using System;
class MainClass
{
static void Main()
{
int a = 5;
a /= 6;
Console.WriteLine(a);
double b = 5;
b /= 6;
Console.WriteLine(b);
}
}
Output
0 0.833333333333333
