R: Integer Functions (Matlab Style)

ceil {pracma} | R Documentation

## Integer Functions (Matlab Style)

### Description

Functions for rounding and truncating numeric values towards near integer values.

### Usage

    ceil(n)
    Fix(n)

### Arguments

`n` | a numeric vector or matrix

### Details

`ceil()` is an alias for `ceiling()` and rounds to the smallest integer equal to or above `n`.

`Fix()` truncates values towards 0 and is an alias for `trunc()`. Uses `ml` prefix to indicate Matlab style.

The corresponding functions `floor()` (rounding to the largest interger equal to or smaller than `n`) and `round()` (rounding to the specified number of digits after the decimal point, default being 0) are already part of R base.

### Value

integer values

### Examples

    x <- c(-1.2, -0.8, 0, 0.5, 1.1, 2.9)
    ceil(x)
    Fix(x)
