# Operators

V supports the following operators:

## Basic Operators

* `+` (addition) for int, float and string
* `-` (subtraction) for int and float
* `*` (multiplication) for int and float
* `/` (division) for int and float
* `%` (modulos) for int
* `=` (assignment) for changing values
* `:=` for initialising values

```
println(3 + 5)
println(2.0 + 5.0)
println('hello' + 'world')

println(9 - 10)
println(7.0 - 5.0)

println(3 * 5)
println(2.0 * 4)

println(23 / 3)
println(25.0 / 5.0)

println(27 % 5)
println(27 % 3)
```

Output

```
8
7.0
hello world

-1
2.0

15
8.0

7
5.0

2
0
```

> Note: Unlike other languages, V doesn't allow modulus with float.

## Comparison Operators

* `>` greater than
* `<` lesser than
* `==` equal to
* `>=` greater than or equal to
* `<=` lesser than or equal to
* `!=` not equal to

## Boolean Operators

* `&&` and
* `||` or
* `!` not

## Bitwise Operators

* `<<` left bitshift
* `>>` right bitshift
* `&` bitwise and
* `|` bitwise or
* `^` bitwise xor

## Assignments Operators

* `+=` same as `foo = foo + var`
* `-=` same as `foo = foo - var`
* `*=` same as `foo = foo * var`
* `/=` same as `foo = foo / var`
* `&=` same as `foo = foo & var`
* `|=` same as `foo = foo | var`
* `>>=` same as `foo = foo >> var`
* `<<=` same as `foo = foo << var`

## Special Operators

* `in` for membership
* `none` for optional
