Yep - sorry, don't have the reference handy.

For what it's worth, since I do have the reference handy, that's essentially a direct translation of how the Fortran 95 standard defines the NINT intrinsic. About the only difference is that it expands out the ?: operator into an "If x<0 then ... else" sentence.
