Detailed Description

 Converts real-valued field elements to real-valued field elements
of a different precision using the Fortran intrinsic `REAL` function,
`Y = REAL(X, kind=r_<prec>)`. Here `Y` is a real-valued field of
precision `kind=r_<prec>` and `X` is the real-valued field whose
values are to be converted from their defined precision.
