Member Function Documentation

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.

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.

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.
Draft:
This API may be changed in the future versions and was introduced in ICU 62
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.

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.
