Integer

Integer Class

Objects of Integer class represent signed and unsigned integers of the C types int and long int.

Instance Variables

value

The value is the formatted representation of the receiver.

Instance Methods

!= (int i)

Return TRUE if the receiver and the argument are not equal, FALSE otherwise.

& (int i)

As a binary operator, perform a bitwise and of the receiver and the argument. The Object class’s & method overloads C’s unary “address of” prefix operator. See Object.

% (int i)

Return an Integer that is the modulus of the receiver and the argument.

%= (int i)

Perform a modulus of the receiver and its argument, and store the result in the receiver. Returns the receiver.

&& (int i)

Return TRUE if the receiver and the argument evaluate to TRUE.

&= (Integer i)

Perform a bitwise and of the receiver and the argument, and assign the result to the receiver.

+ (int i)

Add i and the receiver, as in this example.

++ (void)

Postfix and prefix increment operators for Integer objects.

+= (int arg)

Add the value of arg to the receiver.

- (int i)

Subtract i from the receiver.

- (void)

When used as a unary minus prefix operator, negate the expression.

-- (void)

Postfix and prefix decrement operators for Integer objects.

-= (Integer arg)

Subtract the value of arg from the receiver.

* (int i)

Multiply the receiver by i.

*= (int arg)

Multiply the receiver by arg.

/ (int i)

Divide the receiver by i.

/= (int arg)

Divide the receiver by arg.

< (int i)

Return TRUE if the receiver is less than the argument, FALSE otherwise.

<< (int i)

Perform an arithmetic left shift on the receiver by the number of bits in the argument.

<= (int i)

Return TRUE if the receiver is less than or equal to the argument, FALSE otherwise.

= (int i)

Set the value of the receiver object to i. Also checks for Symbol pointer contexts and other aliases.

intObject = 2;

resultInt = intObject + intObject;

== (int i)

Return TRUE if the receiver and the argument are equal, FALSE otherwise.

> (int i)

Return TRUE if the receiver is greater than the argument, FALSE otherwise.

>= (int i)

Return TRUE if the receiver is greater than or equal to the argument, FALSE otherwise.

>> (int i)

Perform an arithmetic right shift on the receiver by the number of bits in the argument.

^ (int i)

Return the result of a bitwise xor of the receiver and its argument.

^= (int i)

Preform a bitwise xor of the receiver with its argument, and assign the value to the receiver. Returns the receiver.

bitComp (int i)

Return the bitwise complement of the receiver.

invert (void)

Return TRUE if the receiver evaluates to FALSE, FALSE if the receiver evaluates to TRUE.

| (int i)

Perform a bitwise or of the receiver and the argument.

|= (Integer i)

Perform a bitwise or of the receiver and the argument, and assign the result to the receiver.

|| (int i)

Return TRUE if either the receiver or the argument, or both, evaluate to TRUE.

^ (int i)

Perform a bitwise exclusive or of the receiver and the argument.

Returns a String formatted as a decimal or hexadecimal integer. The asString method is a synonym for asDecimalString.

~ (void)

When used to overload C’s ‘~’ operator, is synonymous with the bitComp method, above.
