NumberFormatting

Number formatting and parsing sample

This sample demonstrates how to use the DecimalFormatter, CurrencyFormatter, PercentFormatter and PermilleFormatter classes in the Windows.Globalization.NumberFormatting namespace to display and parse numbers, currencies, and percent values.

The sample also shows how to:

• Round and pad numbers using the many rounding algorithms (enumerated in RoundingAlgorithm) supported by the IncrementNumberRounder and SignificantDigitsNumberRounder classes.
• Use the NumeralSystemTransator class to convert strings containing Latin numbers to an appropriate numeral system that can be rendered in an app which does not perform any digit substitution.
• Use language names with Unicode extensions to directly set properties of number formatters.

The Windows.Globalization.NumberFormatting namespace provides number formatting and parsing APIs that generate strings for display that respect either the current user's preferences, or a caller-specified language(s) and region. There are individual methods for formatting or parsing numbers in the form of decimals, currencies, percentages, and units per thousand (permillages).

Note The Windows universal samples require Visual Studio 2015 to build and Windows 10 to execute.

Build the sample

1. If you download the samples ZIP, be sure to unzip the entire archive, not just the folder with the sample you want to build.
2. Start Microsoft Visual Studio 2015 and select File > Open > Project/Solution.
3. Starting in the folder where you unzipped the samples, go to the Samples subfolder, then the subfolder for this specific sample, then the subfolder for your preferred language (C++, C#, or JavaScript). Double-click the Visual Studio 2015 Solution (.sln) file.
4. Press Ctrl+Shift+B, or select Build > Build Solution.

Run the sample

The next steps depend on whether you just want to deploy the sample or you want to both deploy and run it.

Deploying the sample

• Select Build > Deploy Solution.

Deploying and running the sample
