This will return 2.

1 + 2 + 3

This will return 6.

Minus

The minus operator is used to subtract two numbers. Examples:

1 - 1

This will return 0.

1 - 2 - 3

This will return -4.

Multiply

The multiply operator is used to multiply two numbers. Examples:

1 * 1

This will return 1.

1 * 2 * 3

This will return 6.

Divide

The divide operator is used to divide two numbers. Examples:

1 / 1

This will return 1.

100 / 10 / 2

This will return 5.

Power

The power operator is used to raise a number to a power. Examples:

2 ^^ 2

This will return 4.

2 ^^ 3

This will return 8.

Chaining of arithmetic operators

Multiple different arithmetic operators can be chained together. Examples:

1 + 1 * 2 ^^ 2

This will return 5.

1 + 1 * 2 ^^ 2 / 2

This will return 3.

Advanced arithmetic operators

Left shift

The left shift operator is used to shift a number to the left. Examples:

1 << 1

This will return 2.

1 << 2

This will return 4.

Right shift

The right shift operator is used to shift a number to the right. Examples:

1 >> 1

This will return 0.

1 >> 2

This will return 0.

Comparison operators

Equals

The equals operator is used to check if two values are equal. Examples:

1 == 1

This will return true.

1 == 2

This will return false. Note: The equals operator can only be used to compare two values of the same type.

Not equals

The not equals operator is used to check if two values are not equal. Examples:

1 != 1

This will return false.

1 != 2

This will return true. Note: The not equals operator can only be used to compare two values of the same type.

Greater than

The greater than operator is used to check if a value is greater than another value. Examples:

1 > 1

This will return false.

1 > 2

This will return false.

2 > 1

This will return true.

Less than

The less than operator is used to check if a value is less than another value. Examples:

1 < 1

This will return false.

1 < 2

This will return true.

2 < 1

This will return false.

Greater than or equal to

The greater than or equal to operator is used to check if a value is greater than or equal to another value. Examples:

1 >= 1

This will return true.

1 >= 2

This will return false.

2 >= 1

This will return true.

Less than or equal to

The less than or equal to operator is used to check if a value is less than or equal to another value. Examples:

1 <= 1

This will return true.

1 <= 2

This will return true.

2 <= 1

This will return false.

Logical operators

And

The and operator is used to check if two values are true. Examples:

true and true

This will return true.

true and false

This will return false.

false and true

This will return false.

false and false

This will return false.

Or

The or operator is used to check if one of two values is true. Examples:

true or true

This will return true.

true or false

Not

The not operator is used to check if a value is false. Examples:

not true

This will return false.

not false

Xor

The xor operator is used to check if one of two values is true, but not both. Examples:

true xor true

This will return false.

true xor false

Bitwise operators

Bitwise and

The bitwise and operator performs a bitwise and operation on two numbers. Examples:

1 & 1

This will return 1.

1 & 2

This will return 0.

Bitwise or

The bitwise or operator performs a bitwise or operation on two numbers. Examples:

1 | 1

This will return 1.

1 | 2

This will return 3.

Bitwise xor

The bitwise xor operator performs a bitwise xor operation on two numbers. Examples:

1 ^ 1

This will return 0.

1 ^ 2

This will return 3.

Type operators

Type of

The type of operator is used to get the type of a value. Examples:

typeof 1

This will return Int.

typeof "Hello, world!"

This will return String.

Is

The is operator is used to check if a value is of a certain type. Examples:

1 is Int

This will return true.

1 is String

This will return false.

Variables

Assigning a value to a variable

The equals operator is used to assign a value to a variable. Examples:

a = 1

This will assign 1 to the variable a.

a = 1 + 1

This will assign 2 to the variable a.

Reading a variable

A variable can be read by using its name. Examples:

a = 1
a

This will return 1.

a = 1 + 1
a

This will return 2.
