Field Value

OpCode

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
58	add	Adds two numeric values, returning a new numeric value.

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; value1 is added to value2.

4. The result is pushed onto the stack.

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

Integer addition 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 is 0 rather than 256.

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

The acceptable operand types and their corresponding result data type are listed in the table below. If there is no entry for a particular type combination (for example, int32 and float; int32 and int64), it is an invalid Microsoft Intermediate Language (MSIL) and generates an error.

operand	value1 type	value2 type	result type
add	int32	int32	int32
add	int32	native int	native int
add	int32	&	&
add	int32	*	*
add	int64	int64	int64
add	native int	int32	native int
add	native int	native int	native int
add	native int	&	&
add	native int	*	*
add	F	F	F
add	&	int32	&
add	&	native int	&
add	*	int32	*
add	*	native int	*
