OpCodes.Cgt_Un Field

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Compares two unsigned or unordered values. If the first value is greater than the second, the integer value 1 (int32) is pushed onto the evaluation stack; otherwise 0 (int32) is pushed onto the evaluation stack.

Description

FE 03

cgt.un

Pushes 1 if value1 is greater 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; cgt.un tests if value1 is greater than value2.

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

An int32 value of 1 is pushed on the stack if any of the following is true :

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

For integer values, value1 is strictly greater 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 cgt.un opcode:

  • ILGenerator.Emit(OpCode)
