Subtracts one value from another and pushes the result onto the evaluation stack.
[Visual Basic] Public Shared ReadOnly Sub As OpCode [C#] public static readonly OpCode Sub; [C++] public: static OpCode Sub; [JScript] public static var Sub : OpCode;
The following table lists the instruction's hexadecimal and Microsoft Intermediate Language (MSIL) assembly format, along with a brief reference summary:
|59||sub||Subtracts one value from another, returning a new numeric value.|
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; value2 is subtracted from value1.
- The result is pushed onto the stack.
Overflow is not detected for integer operations (for proper overflow handling, see Sub_Ovf).
Integer subtraction wraps, rather than saturates. For example: assuming 8-bit integers, where value1 is set to 255 and value2 is set to 1, the "wrapped" result will be 0 rather than 256.
Floating-point overflow returns +inf (PositiveInfinity) or -inf (NegativeInfinity).
The following Emit constructor overload can use the sub opcode:
