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

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

x, y | Numeric vectors to compare |
---|---|

tol | Tolerance of comparison. |

sqrt(2) ^ 2 == 2#> [1] FALSEnear(sqrt(2) ^ 2, 2)#> [1] TRUE
