Correct a rounding error in RDS (rprparse).

* Bug: In <rds>, in rprparse::RdrTranslateParam(), add 0.5 before casting
    a double into a long, to avoid rounding error (truncation) for the
    returned value. Patch contributed by N. Shimizu.
      This is mainly due because when parsing the <.rds>, the sscanf may
    slighly change numbers. For example, 0.09 will be parsed as a double
    0.089999999999999997. Then later multiplations fall short when
    truncated into integers.
