Migration Notes
With the integration of Scala.js, the library needed to be broken down into a few sub projects. This requires a slight change to how the console needs to be loaded. The correct command is now:
sbt squantsJVM/consoleVector has been renamed to SVector and now provides the factory methods for both Quantity and Double based vectors. User code that creates vectors should be modified to use this factory.
π The improvements to Vectors also removed the various experiments for dimensional conversion. These improvements are significant but still contain experimental API features which are subject to change.π The support for generic numbers will exist only in test code for the project until we move on to 0.7.x development. Prior to that change, a 0.6.x release will be cut that will based on the old (Double) model. The goal will be to fully implement this feature during 0.7.x development.

v0.5.3 Changes
June 11, 2015June 11, 2015
- β¨ Enhance Quantity model to preserve the unit used in creating the value
- π Rename
UnitMultipliertrait toUnitConverter, themultiplierfield toconversionFactor, and set access level of all fields to protected (see Migration notes) - π Rename
QuantityCompaniontoDimension - π Rename
Quantity.valueUnittounit - π Rename
MassFlowRatetoMassFlow - π Rename
VolumeFlowRatetoVolumeFlow - β Add
dimensionvalue to Quantity - π Improvements to
TimeIntegralandTimeDerivativetraits - β Addition of
TimeSquared, an intermediate non-quantity value, andSecondTimeDerivative,SecondTimeIntegraltraits, all in support of second order time derivatives conversions. - β Addition of
Acceleration.analyze()method - a candidate for a generic SecondTimeDerivative feature. - Addition of
KineticEnergymethod which takesMassandVelocityand applies the conversion (Mass, Velocity) => 1/2(Mass * Velocity * Velocity) yielding anEnergyvalue. - β Addition of
KineticEnergymethod which takesMassandMomentumand applies the conversion (Mass, Momentum) => Momentum / (2 * Mass), yielding anEnergyvalue. - β Addition of
MassunitsKilopoundsandMegapounds - β Addition of
PowerRampunitsWattsPerMinuteandKilowattsPerMinutes - β Addition of

toStringmethods from a few classes - β‘οΈ Update
Length/Area/Volumeoperations to be unit-sensitive - π Rename
CubicMilestoCubicUsMiles - Modify constants to use Exp notation where appropriate
- β‘οΈ Update Scala versions to 2.11.6 and 2.10.5
- β Add support for converting
Quantityvalues to aTuple2and initializing aQuantityfrom a Tuple. - β Addition of
PressureChangedimension - Correction of
Bars/Pascalsconversion factor
Thanks to Steve Barham for his contributions.
Migration Notes
β‘οΈ The change from
UnitMultipler/multiplier->UnitConverter/conversionFactorwill only affect user code where newQuantityorUnitOfMeasuretypes have been created. That code should only need to be updated to reflect the new names. Code that only uses built-in quantities and units should not be affected.Modifications to the
TimeIntegralandTimeDerivativehide the previously visiblechangeandtimefields, which are generally not useful in user code, but may affect Quantity implementations. In addition the TimeIntegral./() implementations have been replaced by a standard implementation within the trait.π¦ The
ElementaryConstantvalue has been moved to theelectropackage.β‘οΈ The renaming of Dimension, MassFlow, VolumeFlow, and CubicUsMiles may require user code to be updated.
β‘οΈ The update to the Quantity model - to preserve the unit used when creating, and rename valueUnit->unit - may affect some users that were accessing the valueUnit directly. Which should generally not be used directly access by user code. This will affect user code used to create new Dimensions, Quantities and Units.

v0.4.2 Changes
July 06, 2014π Improvements to Market
- β Add
Price.inmethod for directly converting a price to a different currency - β Add
Price.toString(unit)method to support formatting in a specific unit - β Add
Money.toStringoverload to support formatting in a different currency - π¨ Refactor Currencies to be objects rather than vals (no change in usage)
- β Add
Currency./method for creating exchange rates - β Add MoneyNumeric
- β Add Comparisons for cross-currency Money values (
==#,!=#,<#,<=#,>#,>=#)
Other General Improvements
- β Add
Quantity.toStringoverload that supports standard number formatting (ie, "%3.2f") - β Add
βas another approx operator - β Add SquantifiedBigDecimal, remove SquantifiedNumeric
- Factor out common data and behavior to new
QuantityCompaniontrait - implemented for all data types exceptMoneywhich currently requires special handling - π Implement
String => Quantityparsing conversions returningTry[Quantity]for all existing types (see Migration Notes below) - β Additional Units:
- ElectricCharge:
MilliampereHours,MilliampereSeconds
- ElectricCharge:
- β Add
unapplytoUnitOfMeasuretrait and deprecate existing extractors in its favor - β Json Serialization - experimental, test code only
- β Generic Quantity Value - experimental, test code only
- β Add support for Scala cross-version builds (2.10 and 2.11) with 2.11.1 as the default
π Bug fixes
- π Fixed
SquareInches.symbol
Migration Note
π Quantity String Parsing
π String parsers no longer return
Either[String, Q]but will return aTry[Q]instead (whereQis the specific quantity type). For example,Mass("10 kg")will return aTry[Mass].π On failure the
Try.failedwill contain aQuantityStringParseExceptionwhich includes the original string to be parsed. This could be used to recover using an alternative parser.Quantity Value Model Unification
π¨ Quantity types implemented as case classes which stored the ratio components of their value (i.e.
Velocity(length, time)) have been refactored to have a single underlying value.β This reduction of all types to a single underlying value has resulted in some loss of precision - reflected in the use of more "approximately equal to" tests. However, this change is a precursor to future work that will support far better precision.
TemperatureandMoneyremain as exceptions to the prevailing model. - β Add
