Types

`define Sum(left: int, right: int)`

Deferred sum. Enables operator precedence by delaying evaluation.

left: int: Left operand
right: int: Right operand

`define Difference(left: int, right: int)`

Deferred difference. Enables operator precedence by delaying evaluation.

left: int: Left operand
right: int: Right operand

`define Product(left: int, right: int)`

Deferred product. Enables operator precedence by delaying evaluation.

left: int: Left operand
right: int: Right operand

`define Quotient(left: int, right: int)`

Deferred quotient. Enables operator precedence by delaying evaluation.

left: int: Left operand
right: int: Right operand

Operators

`operator +(left: int, right: int) returns Sum`

Addition. Lower precedence than multiplication and division.

left: int: Left addend
right: int: Right addend

`operator -(left: int, right: int) returns Difference`

Subtraction. Lower precedence than multiplication and division.

left: int: Minuend
right: int: Subtrahend

`operator *(left: int, right: int) returns Product`

Multiplication. Higher precedence than addition and subtraction.

left: int: Left factor
right: int: Right factor

`operator /(left: int, right: int) returns Quotient`

Division. Higher precedence than addition and subtraction.

left: int: Dividend
right: int: Divisor

`operator div(left: int, right: int) returns int`

Integer division, truncating toward zero.

left: int: Dividend
right: int: Divisor

`operator mod(left: int, right: int) returns int`

Modulo (remainder after integer division).

left: int: Dividend
right: int: Divisor

`operator =(left: int, right: int) returns bool`

Equality comparison.

left: int: Left operand
right: int: Right operand

`operator <>(left: int, right: int) returns bool`

Inequality comparison.

left: int: Left operand
right: int: Right operand

`operator <(left: int, right: int) returns bool`

Less than comparison.

left: int: Left operand
right: int: Right operand

`operator >(left: int, right: int) returns bool`

Greater than comparison.

left: int: Left operand
right: int: Right operand

`operator <=(left: int, right: int) returns bool`

Less than or equal comparison.

left: int: Left operand
right: int: Right operand

`operator >=(left: int, right: int) returns bool`

Greater than or equal comparison.

left: int: Left operand
right: int: Right operand

Functions

`function -(right: int) returns int`

Unary negation.

right: int: Value to negate

`function +(right: int) returns int`

Unary plus (identity).

right: int: Value to return unchanged

`function abs(x: int) returns int`

Absolute value.

x: int: Value whose absolute value to compute
