Solidity is a statically typed language, which means that the type of each
|
|
variable (state and local) needs to be specified.
|
|
Solidity provides several elementary types which can be combined to form complex types.
|
|
|
|
In addition, types can interact with each other in expressions containing
|
|
operators. For a quick reference of the various operators, see :ref:`order`.
|
|
|
|
The concept of "undefined" or "null" values does not exist in Solidity, but newly
|
|
declared variables always have a :ref:`default value<default-value>` dependent
|
|
on its type. To handle any unexpected values, you should use the :ref:`revert function<assert-and-require>` to revert the whole transaction, or return a
|
|
tuple with a second ``bool`` value denoting success.
