Some programming languages provide a complex data type for complex number storage and arithmetic as a built-in (primitive) data type. In some programming environments the term complex data type (in contrast to primitive data types) is a synonym for the composite data type.
Method and apparatus for reading data from and writing data to external systems by virtual machines
This invention discloses a method and apparatus for a virtual machine to read data from an external system and write data, relating to the field of computer technology. One specific implementation of the method includes: creating an address buffer within a smart contract running on the virtual machine; using the storage address of external data as an input parameter of the smart contract; reading external data from the storage address of the external data into the address buffer; wherein the storage address is of integer type; enabling the transfer of complex external data types to the smart contract executed by the Webassembly virtual machine. Another specific implementation includes: using the data address of the address buffer as an output parameter of the smart contract running on the virtual machine; passing the data address to an external system; wherein the output parameter is of integer type; after the external system creates an external buffer, copying the data from the data address to the external buffer; enabling the transfer of complex data types from the Webassembly virtual machine smart contract to the external system.
