numeric

object numeric extends NumericValidate with NumericInference

Module for numeric predicates. Predicates that take type parameters support both shapeless' natural numbers (Nat) and numeric singleton types (which are made available by shapeless' Witness - abbreviated as W in refined) which include subtypes of Int, Long, Double, Char etc.

Example: 

scala> import shapeless.nat._
     | import shapeless.tag.@@
     | import eu.timepit.refined.numeric._

scala> refineMT[Greater[_5]](10)
res1: Int @@ Greater[_5] = 10

scala> refineMT[Greater[W.`1.5`.T]](1.6)
res2: Double @@ Greater[W.`1.5`.T] = 1.6

Type Members

  1. case class Greater[N](n: N) extends Product with Serializable

    Predicate that checks if a numeric value is greater than N.

  2. type GreaterEqual[N] = Not[Less[N]]

    Predicate that checks if a numeric value is greater than or equal to N.

  3. case class Less[N](n: N) extends Product with Serializable

    Predicate that checks if a numeric value is less than N.

  4. type LessEqual[N] = Not[Greater[N]]

    Predicate that checks if a numeric value is less than or equal to N.

  5. type Negative = Less[_0]

    Predicate that checks if a numeric value is negative (< 0).

  6. type NonNegative = Not[Negative]

    Predicate that checks if a numeric value is zero or positive (>= 0).

  7. type NonPositive = Not[Positive]

    Predicate that checks if a numeric value is zero or negative (<= 0).

  8. type Positive = Greater[_0]

    Predicate that checks if a numeric value is positive (> 0).
