object numeric extends 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 eu.timepit.refined.api.Refined
     | import eu.timepit.refined.numeric.Greater
     | import shapeless.nat._5

scala> refineMV[Greater[_5]](10)
res1: Int Refined Greater[_5] = 10

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

Note: generic.Equal can also be used for numeric types.

Type Members

  1. type Divisible[N] = Modulo[N, _0]

    Predicate that checks if an integral value is evenly divisible by N.

  2. type Even = Modulo[shapeless.Nat._2, _0]

    Predicate that checks if an integral value is evenly divisible by 2.

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

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

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

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

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

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

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

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

  7. final case class Modulo[N, O](n: N, o: O) extends Product with Serializable

    Predicate that checks if an integral value modulo N is O.

  8. type Negative = Less[_0]

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

  9. type NonDivisible[N] = Not[Divisible[N]]

    Predicate that checks if an integral value is not evenly divisible by N.

  10. final case class NonNaN() extends Product with Serializable

    Predicate that checks if a floating-point number value is not NaN.

  11. type NonNegative = Not[Negative]

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

  12. type NonPositive = Not[Positive]

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

  13. type Odd = Not[Even]

    Predicate that checks if an integral value is not evenly divisible by 2.

  14. type Positive = Greater[_0]

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