OpCodes.Clt_Un Field

 

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.

Namespace:   System.Reflection.Emit

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)
