Hi Kermit,

No, I believe the documentation is right in this case.

The JJRobot.d_rnd() function takes a double as an argument and returns
a double. The returned value is rounded to the nearest integer (but
is still returned as a double).

It is defined in the source code like this:

static protected final double d_rnd(double value) {
return Math.floor(value + 0.5d);
}


Cheers, Tim.
