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 Bengali digits

```rust use icu::decimal::FixedDecimalFormatter; use icu::locid::locale; use writeable::Writeable;

let provider = icutestdata::getprovider(); let fdf = FixedDecimalFormatter::trynewwithbufferprovider(&provider, &locale!("bn").into(), Default::default()) .expect("Data should load successfully");

let fixeddecimal = 1000007.into(); let formattedvalue = fdf.format(&fixeddecimal); let formattedstr = formattedvalue.writeto_string();

asserteq!("১০,০০,০০৭", formattedstr); ```

Format a number with digits after the decimal separator

```rust use fixed_decimal::FixedDecimal; use icu::decimal::FixedDecimalFormatter; use icu::locid::Locale; use writeable::Writeable;

let provider = icutestdata::getprovider(); let fdf = FixedDecimalFormatter::trynewwithbufferprovider(&provider, &Locale::UND.into(), Default::default()) .expect("Data should load successfully");

let fixeddecimal = FixedDecimal::from(200050) .multipliedpow10(-2);

asserteq!("2,000.50", fdf.format(&fixeddecimal).writetostring()); ```

Format a number using an alternative numbering system

Numbering systems specified in the -u-nu subtag will be followed as long as the locale has symbols for that numbering system.

```rust use icu::decimal::FixedDecimalFormatter; use icu::locid::Locale; use writeable::Writeable;

let provider = icutestdata::getprovider(); let locale = "th-u-nu-thai".parse::().unwrap(); let fdf = FixedDecimalFormatter::trynewwithbufferprovider(&provider, &locale.into(), Default::default()) .expect("Data should load successfully");

let fixeddecimal = 1000007.into(); let formattedvalue = fdf.format(&fixeddecimal); let formattedstr = formattedvalue.writeto_string();

asserteq!("๑,๐๐๐,๐๐๗", formattedstr); ```
