OpCodes.Clt_Un Field
Updated: June 2010
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
Assembly: mscorlib (in mscorlib.dll)

clt.un |
Pushes 1 if value1 is less than value2; else pushes 0 (unsigned values). |
The stack transitional behavior, in sequential order, is:
-
value1 is pushed onto the stack.
-
value2 is pushed onto the stack.
-
value2 and value1 are popped from the stack; clt.un tests if value1 is less than value2.
-
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)
