TolerantNumerics

trait TolerantNumerics extends AnyRef

Provides Equality and Equivalence instances for Numeric types that compare for equality with a given tolerance.

Here's an example:

scala> import org.scalautils._
import org.scalautils._
scala> import TripleEquals._
import TripleEquals._
scala> 2.001 === 2.0
res0: Boolean = false
scala> implicit val doubleEquality = TolerantNumerics.tolerantDoubleEquality(0.01)
doubleEquality: org.scalautils.Equality[Double] = org.scalautils.TolerantNumerics$$anon$1@16c2bd13
scala> 2.001 === 2.0
res1: Boolean = true
