-DESCRIPTION
-<<floor>> and <<floorf>> find
-@tex
-$\lfloor x \rfloor$,
-@end tex
-the nearest integer less than or equal to <[x]>.
-<<ceil>> and <<ceilf>> find
-@tex
-$\lceil x\rceil$,
-@end tex
-the nearest integer greater than or equal to <[x]>.
-
-RETURNS
-<<floor>> and <<ceil>> return the integer result as a double.
-<<floorf>> and <<ceilf>> return the integer result as a float.
-
-PORTABILITY
-<<floor>> and <<ceil>> are ANSI.
-<<floorf>> and <<ceilf>> are extensions.
