Available extensions

Values

up → const RoundingMode

Upward rounding (away from zero) Examples for integers:

  • -2.3 -> -3
  • 2.3 -> 3
  • 0.0 -> 0
  • 0.0000001 -> 1
  • -0.0000001 -> -1
down → const RoundingMode

Downward rounding (towards zero) Examples for integers:

  • -2.3 -> -2
  • 2.3 -> 2
  • 0.0 -> 0
  • 0.0000001 -> 0
  • -0.0000001 -> 0
ceiling → const RoundingMode

Ceiling rounding (towards positive infinity) Examples for integers:

  • -2.3 -> -2
  • 2.3 -> 3
  • 0.0 -> 0
  • 0.0000001 -> 1
  • -0.0000001 -> 0
floor → const RoundingMode

Floor rounding (towards negative infinity) Examples for integers:

  • -2.3 -> -3
  • 2.3 -> 2
  • 0.0 -> 0
  • 0.0000001 -> 0
  • -0.0000001 -> -1
halfUp → const RoundingMode

Five up six down (round towards nearest integer, if equidistant round up) Examples for integers:

  • -2.5 -> -3
  • 2.5 -> 3
  • -2.4 -> -2
  • 2.4 -> 2
  • 0.5 -> 1
  • -0.5 -> -1
halfDown → const RoundingMode

Five down six up (round towards nearest integer, if equidistant round down) Examples for integers:

  • -2.5 -> -2
  • 2.5 -> 2
  • -2.6 -> -3
  • 2.6 -> 3
  • 0.5 -> 0
  • -0.5 -> 0
halfEven → const RoundingMode

Five to even (round towards nearest integer, if equidistant round to even) Examples for integers:

  • -2.5 -> -2
  • 2.5 -> 2
  • -3.5 -> -4
  • 3.5 -> 4
  • -2.6 -> -3
  • 2.6 -> 3
  • 0.5 -> 0
  • 1.5 -> 2
unnecessary → const RoundingMode

Assert that no rounding is necessary Examples for integers:

  • -2.0 -> -2
  • 2.0 -> 2
  • -2.3 -> throws ArgumentError
  • 2.3 -> throws ArgumentError
