// See Also: bosl_version_num(), bosl_version_str(), bosl_required()
// Usage:
// ver = bosl_version();
// Description:
// Returns a list with three integer elements, [MAJOR,MINOR,REV],
// representing the Major, Minor, and Build Revision numbers.
// For example, version 2.1.43 will be returned as `[2,1,43]`.

// Description:
// Returns a floating point number of the version, formatted like M.mmrrrr where M is the major version number,
// each m is a zero-padded digit of the minor version number, and each r is a zero-padded digit of the build
// revision number. For example, version 2.1.43 will be returned as `2.010043`.
