Memory Operations

Get two integers from the user,   and then (for those two integers), display their:

•   sum
•   difference
•   product
•   integer quotient
•   remainder
•   exponentiation   (if the operator exists)

Don't include error handling.

For quotient, indicate how it rounds   (e.g. towards zero, towards negative infinity, etc.).

For remainder, indicate whether its sign matches the sign of the first operand or of the second operand, if they are different.

Negative quantities are held in two's-complement form. Multiplication: The product of the multiplier (the second operand) and the multiplicand (the first operand) replaces the multiplicand. Both multiplier and multiplicand are 32-bit signed integers. The product is always a 64-bit signed integer and occupies an even/odd register pair. Division: The dividend (first operand) is divided by the divisor (second operand) and replaced by the quotient and remainder. The dividend is a 64-bit signed integer and occupies the even/odd pair of registers. A 32-bit signed remainder and a 32-bit signed quotient replace the dividend in the even-numbered and odd-numbered registers, respectively. The sign of the quotient is determined by the rules of algebra. The remainder has the same sign as the dividend. * Arithmetic/Integer 04/09/2015ARITHINT CSECT USING ARITHINT,R12 LR R12,R15ADD L R1,A A R1,B r1=a+b XDECO R1,BUF MVI BUF,C'+' XPRNT BUF,12SUB L R1,A S R1,B r1=a-b XDECO R1,BUF MVI BUF,C'-' XPRNT BUF,12MUL L R1,A M R0,B r0r1=a*b XDECO R1,BUF so r1 has the lower part MVI BUF,C'*' XPRNT BUF,12DIV L R0,A SRDA R0,32 to shift the sign D R0,B r1=a/b and r0 has the remainder XDECO R1,BUF so r1 has quotient MVI BUF,C'/' XPRNT BUF,12MOD L R0,A SRDA R0,32 to shift the sign D R0,B r1=a/b and r0 has the remainder XDECO R0,BUF so r0 has the remainder MVI BUF,C'R' XPRNT BUF,12RETURN XR R15,R15 BR R14 CNOP 0,4A DC F'53'B DC F'11'BUF DC CL12' ' YREGS END ARITHINT Inputs are in the code: a=53, b=11 Output: + 64 - 42 * 583 / 4 R 9  ## 6502 Assembly Code is called as a subroutine (i.e. JSR Arithmetic).

This operator is equivalent to the OVERAB operator of the revised report, except it delivers the remainder as a result. So a '/:=' b sets a to the quotient of a%b and returns the remainder of a%b as a result (Note "%" is the division operator in Algol 68, not the modulo operator - it can also be written as OVER). This operator must be "stropped" i.e. enclosed in single quotes. eg. INT quotient:=355, remainder; remainder := quotient '/:=' 113;  Sets quotient to 3, remainder to 16. ## ALGOL W The Algol W integer division operator (called div) truncates towards zero. The result of the modulo operator (called rem) has the sign of the first operand when the operands have different signs. begin integer a, b; write( "Enter 2 integers> " ); read( a, b ); write( "a + b: ", a + b ); % addition % write( "a -

Mathcad's "whiteboard" interface allows the user to mix formatted text regions with formatted math regions. Text region formatting is fairly arbitrary, individual characters can have their font, font size and bold/italic/underline settings set or changed at will. Math regions use amendable styles to identify variables, functions (normally built-in functions), keywords, system words and units (Mathcad has a units-aware, SI-based quantity system). It really is a simple as 'writing' on the whiteboard. Task Notes For quotient, indicate how it rounds (e.g. towards zero, towards negative infinity, etc.). There is no quotient function in Mathcad, only complex division. We emulate quotient by standard division followed by rounding using both floor, which rounds towards negative infinity, and trunc, which rounds towards zero. For remainder, indicate whether its sign matches the sign of the first operand or of the second operand, if they are different. We use the Mathcad function mod(x,y), which returns x modulo y, and has the same sign as x. Instructions Enter two integers of your choice for Int1 and Int2. (type into the right hand side of the 'Int1:= ' and 'Int2:=' statements, overwriting or modifying any numbers already there) Implementation Mathcad Input and Output Mathcad "standard" input and output takes place directly on a worksheet ("program source code"). Inputs: == the user types in values after := (definition) operator Integer One: Int1:=-8 Integer Two: Int2:=3 Results: == Mathcad automatically calculates and displays results after = (evaluation) operator. sum : Int1 + Int2 = -5 difference : Int1 - Int2 = -11 product : Int1 · Int2 = -24 integer quotient : floor(Int1÷Int2)=-3 trunc(Int1÷Int2)=-2 remainder : mod(Int1,Int2)=-2 exponentiation : Int1Int2=-512 ## MATLAB / Octave disp("integer a: "); a = scanf("%d", 1);disp("integer b: "); b = scanf("%d", 1);a+ba-ba*bfloor(a/b)mod(a,b)a^b ## Maxima block( [a: read("a"), b: read("b")], print(a + b), print(a - b), print(a * b), print(a / b), print(quotient(a, b)), print(remainder(a, b)), a^b); ## MAXScript x = getKBValue prompt:"First number"y = getKBValue prompt:"Second number:" format "Sum: %\n" (x + y) format "Difference: %\n" (x - y) format "Product: %\n" (x * y) format "Quotient: %\n" (x / y) format "Remainder: %\n" (mod x y) ## Mercury  :- module arith_int.:- interface. :- import_module io.:- pred main(io::di, io::uo) is det. :- implementation.:- import_module int, list, string. main(!IO) :- io.command_line_arguments(Args, !IO), ( if Args = [AStr, BStr], string.to_int(AStr, A), string.to_int(BStr, B) then io.format("A + B = %d\n", [i(A + B)], !IO), io.format("A - B = %d\n", [i(A - B)], !IO), io.format("A * B = %d\n", [i(A * B)], !IO), % Division: round towards zero. % io.format("A / B = %d\n", [i(A / B)], !IO), % Division: round towards minus infinity. % io.format("A div B = %d\n", [i(A div B)], !IO), % Modulus: X mod Y = X - (X div Y) * Y. % io.format("A mod B = %d\n", [i(A mod B)], !IO), % Remainder: X rem Y = X - (X / Y) * Y. % io.format("A rem B = %d\n", [i(A rem B)], !IO), % Exponentiation is done using the function int.pow/2. % io.format("A pow B = %d\n", [i(A pow B)], !IO) else io.set_exit_status(1, !IO) ).  ## Metafont string s[];message "input number a: ";s1 := readstring;message "input number b: ";s2 := readstring;a := scantokens s1;b := scantokens s2; def outp(expr op) = message "a " & op & " b = " & decimal(a scantokens(op) b) enddef; outp("+");outp("-");outp("*");outp("div");outp("mod"); end ## min Works with: min version 0.19.3 (concat dup -> ' prepend "1 -> 2" swap % puts!) :show ("Enter an integer" ask int) 2 times ' prepend('+ '- '* 'div 'mod) quote-map ('show concat) map cleave Output: Enter an integer: -3 Enter an integer: 5 (-3 5 +) -> 2 (-3 5 -) -> -8 (-3 5 *) -> -15 (-3 5 div) -> 0 (-3 5 mod) -> -3  ## МК-61/52 П1 <-> П0+ С/ПИП0 ИП1 - С/ПИП0 ИП1 * С/ПИП0 ИП1 / [x] С/ПИП0 ^ ИП1 / [x] ИП1 * - С/ПИП1 ИП0 x^y С/П ## ML/I ML/I will read two integers from 'standard input' or similar, and then output the results to 'standard output' or similar.

NOTES: Some curious aspects of smart BASIC to note in this code example: 1. In smart BASIC, The command INTEG is a true integer function providing only the value of the characteristic. The smart BASIC INT command calculates as a rounding function. This differs from some other versions of BASIC. 2. smart BASIC automatically inserts spaces ahead of and behind numbers. This can cause unexpected formatting issues when combining output from numeric variables with text. In order to suppress the trailing space, you must use the ampersand (&) to concatenate the numeric value with the following text (in this case, a period at the end of each sentence). In the case of leading spaces, you must convert the numeric value to text using the STR command (as with the last line of the code). ## SNOBOL4  output = "Enter first integer:" first = input output = "Enter second integer:" second = input output = "sum = " first + second output = "diff = " first - second output = "prod = " first * second output = "quot = " (qout = first / second) output = "rem = " first - (qout * second)end ## SNUSP As a BF derivative, SNUSP only has increment and decrement as native operations.

This does, however, make it easy to implement addition using negation and subtraction. In this program, we first negate a; then subtract b, and store the result; and finally negate that result, thereby obtaining the sum of the two integers. 00101000000000100000000000000000 0. -20 to c10101000000000010000000000000000 1.

This means there is no such thing as "integer arithmetic" and hence the kludge with int([gets stdin]). Often, these operations would be performed in a different way from what is shown here. For example, to increase the variable "x" by the value of the variable "y", one would write incr x y Also, it's important to surround the arguments to the expr in braces, especially when any of the parts of the expression are not literal constants.

## Wren

In Wren the quotient operator '/' does not round but, when the floor method is applied to the result, it rounds to the lower integer.

The sign of the remainder operator '%' matches the sign of the first operand.

## x86 Assembly

Input and output would be OS-specific and are not implemented. This routine works on the 16-bit 8086, as well as on its 32-bit and 64-bit successors: it could be trivially modified to perform 32-bit or 64-bit arithmetic on machines where those are supported. The quotient is truncated towards zero; the remainder takes its sign from the first operand.
