Member Function Documentation

byDecimal()

static Scale icu::number::Scale::byDecimal ( StringPiece  multiplicand )

static

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.

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.
