In the above expression '( 3 + 5 )' is the first operand for the multiplication operator and ' 2 ' the second.

The one- or two-digit number of the index word or electronic switch was used in the operand of a symbolic machine instruction to specify indexing or as a parameter which is always an index word or electronic switch, e.g., 3.

The operand ' 3 ' is one of the inputs ( quantities ) followed by the addition operator, and the operand ' 6 ' is the other input necessary for the operation.

Based on arity, operators are classified as nullary ( no operands ), unary ( 1 operand ), binary ( 2 operands ), ternary ( 3 operands ) etc.

If there are multiple operations, the operator is given immediately after its second operand ; so the expression written " 3 − 4 + 5 " in conventional infix notation would be written " 3 4 − 5 +" in RPN: first subtract 4 from 3, then add 5 to that.

* Register machine ( 2, 3 ,... operand machine )

For instance, the common register + immediate addressing mode was significantly faster than on the 8086, especially when a memory location was both ( one of the ) operand ( s ) and the destination.

Because one operator and two operands are removed and one operand is added, there is a net loss of one operator and one operand, which still leaves an expression with N operators and N + 1 operands, thus allowing the iterative process to continue.

is an example of commutativity, not associativity, because the operand sequence changed when the 2 and 5 switched places.

The magnetic core memory's cycle time was 5 microseconds ( corresponding roughly to a " clock speed " of 200 kilohertz ; consequently most arithmetic instructions took 10 microseconds ( 100, 000 operations per second ) because they used two memory cycles: one for the instruction, one for the operand data fetch.

Originally, 12-bit instructions included 5 address bits to specify the memory operand, and 9-bit branch destinations.

If the one- or two-digit address of an index word or electronic switch is used or is included in the operand of an XRESERVE or SRESERVE statement ( see page 99 ), the corresponding index word or electronic switch is reserved.

If the symbolic name or actual address of an index word or electronic switch appears or is included in the operand of an XRELEASE or SRELEASE statement ( see page 101 ), the specified index word or electronic switch will again be made available, regardless of the method by which it was reserved.

The first item in the operand, IOCSIXF, is used to specify the first IOCS index word for programs using tape files.

If the first item in the operand is omitted, the symbolic name IOCSIXF will be assigned.

The second item in the operand, IOCSIXG, is used to specify the second IOCS index word for programs using tape files.

If the second item in the operand is omitted, the symbolic name IOCSIXG will be assigned.

The characteristic which distinguishes one register as being the accumulator of a computer architecture is that the accumulator ( if the architecture were to have one ) would be used as an implicit operand for arithmetic instructions.

However, MUL and DIV are special cases, other arithmetic-logical instructions ( ADD, SUB, CMP, AND, OR, XOR, TEST ) may specify any of the eight registers EAX, ECX, EDX, EBX, ESP, EBP, ESI, EDI as the accumulator ( i. e. left operand and destination ); x86 is thus a fairly general register architecture, despite being based on an accumulator model.

The carry is generated by performing an unsigned compare on the result with either operand to see if the result is smaller than either operand.

Note that with ( A0 )+ and -( A0 ), the actual increment or decrement value is dependent on the operand size: a byte access increments the address register by 1, a word by 2, and a long by 4.

#: Unsigned integer divide uses this as the left half of the 128-bit input that is to be divided by the other operand.

In mathematics, an operand is the object of a mathematical operation, a quantity on which an operation is performed.

An operand, then, is also referred to as " one of the inputs ( quantities ) for an operation ".

For a finite collection of two or more numbers, the commutative and associative laws of addition imply that every expression formed using addition only, and in which all members of the collection appear exactly once as operand, has the same value ; this defines the sum of the collection.

An expression enclosed in parentheses is evaluated recursively and treated, for operator association purposes, as a single operand.

The result replaces the expression branch as the second operand of the second < tt >^</ tt >.

For the expression A-B, the right operand must be evaluated and pushed immediately prior to the Minus step.

* expression evaluation is defined to be performed in one of three well-defined methods, indicating whether floating point variables are first promoted to a more precise format in expressions: FLT_EVAL_METHOD == 2 indicates that all internal intermediate computations are performed by default at high precision ( long double ) where available ( e. g. 80 bit double extended ); FLT_EVAL_METHOD == 1 performs all internal intermediate expressions in double precision ( unless an operand is long double ); FLT_EVAL_METHOD == 0 specifies each operation is evaluated only at the precision of the widest operand of each operator.

< u > ora </ u > quotient )(( expression ) left operand, right operand, derivative );

The "" operator is generalized in XPath 2. 0 to allow any kind of expression to be used as an operand: in XPath 1. 0, the right-hand side was always an axis step.

a Poisson bracket of the operand with the Hamiltonian, the expression of the Hamilton's equation

) and the actual operation ( such as add or compare ) and other fields that may give the type of the operand ( s ), the addressing mode ( s ), the addressing offset ( s ) or index, or the actual value itself ( such constant operands contained in an instruction are called immediates ).

In computing, an operand is the part of a computer instruction which specifies what data is to be manipulated or operated on, whilst at the same time representing the data itself.

The mnemonic letter, for memory ( referenced by HL ), was lifted out from within the instruction mnemonic to become a syntactically freestanding operand, while registers and combinations of registers became very inconsistently denoted ; either by abbreviated operands ( MVI D, LXI H and so on ), within the instruction mnemonic itself ( LDA, LHLD and so on ), or both at the same time ( LDAX B, STAX D and so on ).

The contents of an index register is added to ( in some cases subtracted from ) an immediate address ( one that is part of the instruction itself ) to form the " effective " address of the actual data ( operand ).

The term " addressing mode " is itself subject to different interpretations: either " memory address calculation mode " or " operand accessing mode ".

Instead of using an operand from memory, the value of the operand is held within the instruction itself.

Thus, when specifically permitted, the operand of a given line on the Autocoder coding sheet may be continued in the operand of from one to four additional lines which immediately follow.

Some of them were followed by one or two bytes of data, which could be an immediate operand, a memory address, or a port number.

A computer instruction describes an operation such as add or multiply X, while the operand ( or operands, as there can be more than one ) specify on which X to operate as well as the value of X.

Additionally, in assembly language, an operand is a value ( an argument ) on which the instruction, named by mnemonic, operates.

For example, instead of instructions such as load and store, the PDP-11 had a move instruction for which either operand ( source and destination ) could be memory or register.

This process iterates until an operator is resolved, which must happen eventually, as there must be one more operand than there are operators in a complete statement.

On traditional architectures, an instruction includes an opcode specifying the operation to be performed, such as " add contents of memory to register ", and zero or more operand specifiers, which may specify registers, memory locations, or literal data.

* 1-operand ( one-address machines ), so called accumulator machines, include early computers and many small microcontrollers: most instructions specify a single right operand ( that is, constant, a register, or a memory location ), with the implicit accumulator as the left operand ( and the destination if there is one ): load a, add b, store c. A related class is practical stack machines which often allow a single explicit operand in arithmetic instructions: push a, add b, pop c.

The philosophy of many other machines was toward using instructions which were complicated — for example, a single instruction which would fetch an operand from memory and add it to a value in a register.

Additional instructions were supported via the Operate ( Opr ) instruction code, which decoded the constant operand as an extended zero-operand opcode, providing for almost endless and easy instruction set expansion as newer implementations of the transputer were introduced.

Some of them are followed by one or two bytes of data, which could be an immediate operand, a memory address, or a port number.

* One accumulator ( W0 ), the use of which ( as source operand ) is implied ( i. e. is not encoded in the opcode )
