When converting a larger type to a shorter type a runtime exception can occur in case of an overflow. -The following type conversion functions must be available: - - ``u32tobool(x:u32) -> y:bool`` - - ``booltou32(x:bool) -> y:u32`` - - ``u32tou64(x:u32) -> y:u64`` - - ``u64tou32(x:u64) -> y:u32`` - - etc. (TBD) +Truncating conversions are supported between the following types: + - ``bool`` + - ``u32`` + - ``u64`` + - ``u256`` + - ``s256`` + +For each of these a type conversion function exists having the prototype in the form of ``<input_type>to<output_type>(x:<input_type>) -> y:<output_type>``, +such as ``u32tobool(x:u32) -> y:bool``, ``u256tou32(x:u256) -> y:u32`` or ``s256tou256(x:s256) -> y:u256``. .. note:: |
