OpCodes.Clt_Un Field

Definition

Namespace:

System.Reflection.Emit

Assemblies:

netstandard.dll, System.Reflection.Primitives.dll

Source:

OpCodes.cs

Compares the unsigned or unordered values value1 and value2. If value1 is less than value2, then the integer value 1 (int32) is pushed onto the evaluation stack; otherwise 0 (int32) is pushed onto the evaluation stack.

Remarks

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

Format	Assembly Format	Description
FE 05	clt.un	Pushes 1 if value1 is less than value2; else pushes 0 (unsigned values).

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; clt.un tests if value1 is less than value2.

4. If value1 is less than value2, 1 is pushed onto the stack; otherwise 0 is pushed onto the stack.

The clt.un instruction compares value1 and value2. An int32 value of 1 is pushed on the stack if any of the following is true:

• value1 is strictly less than value2 (as for clt).

• For floating-point numbers, value1 is not ordered with respect to value2.

• For integer values, value1 is strictly less than value2 when considered as unsigned numbers.

Otherwise, an int32 value of 0 is pushed on the stack.

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

• ILGenerator.Emit(OpCode)
