# round_half_up: Round a numeric vector; halves will be rounded up, ala... In janitor: Simple Tools for Examining and Cleaning Dirty Data

## Description

In base R `round()`, halves are rounded to even, e.g., 12.5 and 11.5 are both rounded to 12. This function rounds 12.5 to 13 (assuming `digits = 0`). Negative halves are rounded away from zero, e.g., -0.5 is rounded to -1.

This may skew subsequent statistical analysis of the data, but may be desirable in certain contexts. This function is implemented exactly from https://stackoverflow.com/a/12688836; see that question and comments for discussion of this issue.

## Usage

 `1` ```round_half_up(x, digits = 0) ```

## Arguments

 `x` a numeric vector to round. `digits` how many digits should be displayed after the decimal point?

## Examples

 ```1 2 3 4``` ```round_half_up(12.5) round_half_up(1.125, 2) round_half_up(1.125, 1) round_half_up(-0.5, 0) # negatives get rounded away from zero ```
