icu_decimal

Formatting basic decimal numbers.

This module is published as its own crate (icu_decimal) and as part of the icu crate. See the latter for more details on the ICU4X project.

Support for currencies, measurement units, and compact notation is planned. To track progress, follow icu4x#275.

Examples

Format a number with Bangla digits

use icu::decimal::input::Decimal;
use icu::decimal::DecimalFormatter;
use icu::locale::locale;
use writeable::assert_writeable_eq;

let formatter =
    DecimalFormatter::try_new(locale!("bn").into(), Default::default())
        .expect("locale should be present");

let decimal = Decimal::from(1000007);

assert_writeable_eq!(formatter.format(&decimal), "১০,০০,০০৭");

Format a number with digits after the decimal separator

use icu::decimal::input::Decimal;
use icu::decimal::DecimalFormatter;
use icu::locale::Locale;
use writeable::assert_writeable_eq;

let formatter =
    DecimalFormatter::try_new(Default::default(), Default::default())
        .expect("locale should be present");

let decimal = {
    let mut decimal = Decimal::from(200050);
    decimal.multiply_pow10(-2);
    decimal
};

assert_writeable_eq!(formatter.format(&decimal), "2,000.50");

Format a number using an alternative numbering system

Numbering systems specified in the -u-nu subtag will be followed.

use icu::decimal::input::Decimal;
use icu::decimal::DecimalFormatter;
use icu::locale::locale;
use writeable::assert_writeable_eq;

let formatter = DecimalFormatter::try_new(
    locale!("th-u-nu-thai").into(),
    Default::default(),
)
.expect("locale should be present");

let decimal = Decimal::from(1000007);

assert_writeable_eq!(formatter.format(&decimal), "๑,๐๐๐,๐๐๗");
