Kim Haase commented on DERBY-2320:
----------------------------------

Good technical change. But this gives us a chance to correct some preexisting problems with
the sentence (grammar, terminology) . I would suggest changing

You should not expect that the DEGREES(ACOS(0.5)) to exactly equal 60.0.

to

You should not expect DEGREES(ACOS(0.5)) to return exactly 60.0.

> In the description of DEGREES function in Derby Reference Manual, next description exists.
> > Attention: The conversion from radians to degrees is not exact. You should not expect
that the COS(RADIANS(90.0)) to exactly equal 0.0.
> Because the page is for DEGREES function , example here should be DEGREES( ACOS( 0 )
) and 90.0 .
