Syntax

template<typename NumericType>  
struct FNumericUnit

Remarks

FNumericUnit is a numeric type that wraps the templated type, whilst a specified unit. It handles conversion to/from related units automatically. The units are considered not to contribute to the type's state, and as such should be considered immutable once set.

Forward declaration of types defined in UnitConversion.h

Variables

	Type	Name	Description
	const EUnit	Units	The associated units for the value.
	NumericType	Value	The numeric (scalar) value

Constructors

	Type	Name	Description
		FNumericUnit ()	Constructors
		FNumericUnit ( const FNumericUnit& Other )	Copy construction/assignment from the same type
		FNumericUnit ( const FNumericUnit< OtherType >& Other )	Templated Copy construction/assignment from differing numeric types.
		FNumericUnit ( const NumericType& InValue, EUnit InUnits )

Functions

Type	Name	Description
TOptional< FNumericUnit< NumericType > >	ConvertTo ( EUnit ToUnits )	Convert this quantity to a different unit
FNumericUnit< NumericType >	QuantizeUnitsToBestFit ()	Quantizes this number to the most appropriate unit for user friendly presentation (e.g. 1000m returns 1km).
TValueOrError< FNumericUnit< NumericType >, FText >	TryParseExpression ( const TCHAR* InExpression, EUnit InDefaultUnit, const FNumericUnit< NumericType >& InExistingValue )	Try and parse an expression into a numeric unit
TOptional< FNumericUnit< NumericType > >	TryParseString ( const TCHAR* InSource )	Parse a numeric unit from a string

	FNumericUnit &	operator= ( const FNumericUnit& Other )
	FNumericUnit &	operator= ( const FNumericUnit< OtherType >& Other )
	FNumericUnit< NumericType > &	operator= ( const FNumericUnit< OtherType >& Other )
