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:

[The 'ordered' type of list has not been implemented in the ECMA stylesheet.]

Overflow is not detected for integer operations (for proper overflow handling, see OpCodes.Sub_Ovf).

Integer subtraction wraps, rather than saturates. For example: assuming 8-bit integers, where value1 is set to 0 and value2 is set to 1, the "wrapped" result will be 255.

Floating-point overflow returns +inf (PositiveInfinity) or -inf (NegativeInfinity).

The following ILGenerator.Emit(OpCode) method overload can use the sub opcode:
