\description{
Functions for rounding and truncating numeric values towards near
integer values.
}
\usage{
ceil(n)
fix(n)
}
\arguments{
\item{n}{a numeric vector or matrix}
}
\details{
\code{ceil()} is an alias for \code{ceiling()} and rounds to the smallest
integer equal to or above \code{n}.
\code{fix()} truncates values towards 0 and is an alias for \code{trunc()}.
The corresponding functions \code{floor()} (rounding to the largest interger
equal to or smaller than \code{n}) and \code{round()} (rounding to the
specified number of digits after the decimal point, default being 0) are
already part of R base.
