near {dplyr} | R Documentation

## Compare two numeric vectors

### Description

This is a safe way of comparing if two vectors of floating point numbers are (pairwise) equal. This is safer than using `==`, because it has a built in tolerance

### Usage

    near(x, y, tol = .Machine$double.eps^0.5)

### Arguments

`x, y` | Numeric vectors to compare
`tol` | Tolerance of comparison.

### Examples

    sqrt(2) ^ 2 == 2
    near(sqrt(2) ^ 2, 2)
