Crate icu_decimal
source ·Expand description
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 fixed_decimal::SignedFixedDecimal;
use icu::decimal::FixedDecimalFormatter;
use icu::locale::locale;
use writeable::assert_writeable_eq;
let fdf = FixedDecimalFormatter::try_new(
locale!("bn").into(),
Default::default(),
)
.expect("locale should be present");
let fixed_decimal = SignedFixedDecimal::from(1000007);
assert_writeable_eq!(fdf.format(&fixed_decimal), "১০,০০,০০৭");
§Format a number with digits after the decimal separator
use fixed_decimal::SignedFixedDecimal;
use icu::decimal::FixedDecimalFormatter;
use icu::locale::Locale;
use writeable::assert_writeable_eq;
let fdf =
FixedDecimalFormatter::try_new(Default::default(), Default::default())
.expect("locale should be present");
let fixed_decimal = {
let mut decimal = SignedFixedDecimal::from(200050);
decimal.multiply_pow10(-2);
decimal
};
assert_writeable_eq!(fdf.format(&fixed_decimal), "2,000.50");
§Format a number using an alternative numbering system
Numbering systems specified in the -u-nu
subtag will be followed.
use fixed_decimal::SignedFixedDecimal;
use icu::decimal::FixedDecimalFormatter;
use icu::locale::locale;
use writeable::assert_writeable_eq;
let fdf = FixedDecimalFormatter::try_new(
locale!("th-u-nu-thai").into(),
Default::default(),
)
.expect("locale should be present");
let fixed_decimal = SignedFixedDecimal::from(1000007);
assert_writeable_eq!(fdf.format(&fixed_decimal), "๑,๐๐๐,๐๐๗");
