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
44 < int32 >	blt.un target	Branch to the target instruction at the specified offset if the first value is less than the second value (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; if value1 is less than value2, the branch operation is performed.

The blt.un instruction transfers control to the specified target instruction if value1 is less than value2, when compared using unsigned integer or unordered float values. The effect is identical to performing a clt.un instruction followed by a brtrue branch to the specific target instruction. The target instruction is represented as a 4-byte signed offset from the beginning of the instruction following the current instruction.

If the target instruction has one or more prefix codes, control can only be transferred to the first of these prefixes. Control transfers into and out of try, catch, filter, and finally blocks cannot be performed by this instruction.

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