Operators

Ki uses a familiar set of operators.

Boolean Operators

and: &&
or: ||
equivalent: ==
not: !
not equal: !=
less than: <
less than or equal to: <=
greater than: >
greater than or equal to: >=

Mathematical Operators

add: +
subtract: -
multiply: *
divide: /
modulus: %
exponent: **
increment: ++
decrement: --

Any of these (save ++ and --) can have a = appended to the end to assign the new value. For example:

fn main() {
    var x: 5

    x += 11
}

++ and -- are syntactic sugar for += 1 and -= 1, i.e. they culminate in an assignment. As such, they cannot be used in compound expressions, like y = x++. They can also only be used as suffixes, not prefixes.

Bitwise Operators

and: &
or: |
not: ~
xor: ^
shift left: <<
shift right: >>

Just as with the mathematical operators, any of these can also have a = appended to the end to assign the new value. For example:

fn main() {
    var x: 5

    x <<= 2
}
