ICU 77.1: icu::number::Scale Class Reference

A class that defines a quantity by which a number should be multiplied when formatting. More...

#include <numberformatter.h>

struct  impl::MacroProps   struct  impl::MicroProps   class  impl::NumberFormatterImpl   class  impl::MultiplierFormatHandler   class  impl::GeneratorHelpers   class  ::icu::numparse::impl::NumberParserImpl   class  ::icu::numparse::impl::MultiplierParseHandler  

A class that defines a quantity by which a number should be multiplied when formatting.

To create a Scale, use one of the factory methods.

Stable:
ICU 62

Definition at line 1086 of file numberformatter.h.

◆ Scale() [1/3] icu::number::Scale::Scale ( const Scale &  other ) ◆ Scale() [2/3] icu::number::Scale::Scale ( Scale &&  src ) noexcept ◆ ~Scale() icu::number::Scale::~Scale ( ) ◆ Scale() [3/3] icu::number::Scale::Scale ( int32_t  magnitude, impl::DecNum *  arbitraryToAdopt  )
Internal:
Do not use.

This API is for internal use only.

◆ byDecimal()

Multiply numbers by an arbitrary value before formatting.

Useful for unit conversions.

This method takes a string in a decimal number format with syntax as defined in the Decimal Arithmetic Specification, available at http://speleotrove.com/decimal

Also see the version of this method that takes a double.

Returns
A Scale for passing to the setter in NumberFormatter.
Stable:
ICU 62
◆ byDouble() static Scale icu::number::Scale::byDouble ( double  multiplicand ) static

Multiply numbers by an arbitrary value before formatting.

Useful for unit conversions.

This method takes a double; also see the version of this method that takes an exact decimal.

Returns
A Scale for passing to the setter in NumberFormatter.
Stable:
ICU 62
◆ byDoubleAndPowerOfTen() static Scale icu::number::Scale::byDoubleAndPowerOfTen ( double  multiplicand, int32_t  power  ) static

Multiply a number by both a power of ten and by an arbitrary double value.

Returns
A Scale for passing to the setter in NumberFormatter.
Stable:
ICU 62
◆ none() static Scale icu::number::Scale::none ( ) static

Do not change the value of numbers when formatting or parsing.

Returns
A Scale to prevent any multiplication.
Stable:
ICU 62
◆ operator=() [1/2] Scale& icu::number::Scale::operator= ( const Scale &  other ) ◆ operator=() [2/2] Scale& icu::number::Scale::operator= ( Scale &&  src ) noexcept ◆ powerOfTen() static Scale icu::number::Scale::powerOfTen ( int32_t  power ) static

Multiply numbers by a power of ten before formatting.

Useful for combining with a percent unit:

NumberFormatter::with().unit(NoUnit::percent()).multiplier(Scale::powerOfTen(2))
Returns
A Scale for passing to the setter in NumberFormatter.
