About ACOS() and ASIN() in the manual

The manual says -(PI/2)<ACOS(x)<(PI/2), but I think it should be 0<ACOS(x)<PI, or better yet, 0≤ACOS(x)≤PI. I think "≤" (instead of "<") must be used for the description of ASIN() as well.

Hm, I think I just copied it from an older BASIC manual, but I never tried the actual implementations. I will check it.
