Class FPInterval

constructor

• new FPInterval(kind, ...endpoints): FPInterval

• Constructor

  FPTraits.toInterval is the preferred way to create FPIntervals

  Parameters

  • kind: FPKind

    the floating point number type this is an interval for

  • Rest ...endpoints: IntervalEndpoints

    beginning and end of the interval

  Returns FPInterval

Readonly begin

Readonly end

Readonly kind

contains

• contains(n): boolean

• Parameters

  • n: number | FPInterval

  Returns boolean

  if a point or interval is completely contained by this interval

containsZeroOrSubnormals

• containsZeroOrSubnormals(): boolean

• Returns boolean

  if any values in the interval may be flushed to zero, this includes any subnormals and zero itself.

endpoints

• endpoints(): IntervalEndpoints

• Returns IntervalEndpoints

  begin and end if non-point interval, otherwise just begin

isFinite

• isFinite(): boolean

• Returns boolean

  if this interval only contains finite values

isPoint

• isPoint(): boolean

• Returns boolean

  if this interval contains a single point

toString

• toString(): string

• Returns string

  a string representation for logging purposes

traits
