TolerantNumerics

org.scalactic.TolerantNumerics
See theTolerantNumerics companion object

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

Here's an example:

scala> import org.scalactic._
import org.scalactic._

scala> import TripleEquals._
import TripleEquals._

scala> 2.001 === 2.0
res0: Boolean = false

scala> implicit val doubleEquality = TolerantNumerics.tolerantDoubleEquality(0.01)
doubleEquality: org.scalactic.Equality[Double] = org.scalactic.TolerantNumerics$$anon$1@16c2bd13

scala> 2.001 === 2.0
res1: Boolean = true
