OpCodes.Rem_Un Field


Divides two unsigned values and pushes the remainder onto the evaluation stack.

Namespace:   System.Reflection.Emit
Assembly:  mscorlib (in mscorlib.dll)

public static readonly OpCode Rem_Un

The following table lists the instruction's hexadecimal and Microsoft Intermediate Language (MSIL) assembly format, along with a brief reference summary:


Assembly Format




Pushes the remainder of dividing unsigned value1 by unsigned value2 onto the stack.

The stack transitional behavior, in sequential order, is:

  1. value1 is pushed onto the stack.

  2. value2 is pushed onto the stack.

  3. value2 and value1 are popped from the stack and the remainder of value1 div value2 computed.

  4. The result is pushed onto the stack.

result = value1 rem.un value2 satisfies the following conditions:

result = value1 - value2 x(value1 div.un value2), and:

0 = result < value2, where div.un is the unsigned division instruction.

The rem.un instruction computes result and pushes it on the stack. Rem.un treats its arguments as unsigned integers, while Rem treats them as signed integers.

Rem.un is unspecified for floating-point numbers.

Integral operations throw DivideByZeroException if value2 is zero.

The following Emit method overload can use the rem.un opcode:

  • ILGenerator.Emit(OpCode)
