Operators
Binary Operators¶
These are all the operations supposorted by Yona's binary operators. Combinations of other data types than listed here will result in a TypeError.

Unary operators¶
In addition to the binary operators in the table above, Yona supports negation operator ~ which can be applied either to integer or boolean values and will result in bitwise complement, or boolean negation respectively.
