hmsToRadians( hour, min, sec )In conversions of this type, one has to be careful to get the
sign right in converting angles which are between 0 and -1 hours.
This routine uses the sign bit of the hour argument,
taking care to distinguish between +0 and -0 (their internal
representations are different for floating point values).
