# Float64 Scalar Data Accessor Interface 1 (Float64 SDAI1)
Specification Document
(org.vcssl.connect.Float64ScalarDataAccessorInterface1)

## Abstract

Float64 Scalar Data Accessor Interface 1 (Float64 SDAI1) is a data-I/O interface, mainly implemented by data container objects of language processor systems.

In this org.vcssl.connect package, multiple data I/O interfaces are provided for passing/receiving data without any data-conversions, between script-engine-side and plug-in-side, if required.

In them, this interface Float64 SDAI1 provides I/O methods of a double-type (64-bit floating point number type) scalar value.

## Status

The status of this interface is "FINALIZED".

The specification of this interface had been finalized at 2022/08/31. No modifications will be applied for this interface, excluding documents/comments.

This interface is currently supported by the scripting engine of Vnano. You can use this interface for development of plug-ins of applications equipped with the Vnano engine.

## License

This interface is published under CC0, which is almost the same as the so-called "copyright-free" (domain).
