Specification

Available namespaces are:

• Ada.Numbers.Settings which contains the settings for the converters;
• Ada.Numbers.Converters which contains the extension methods for conversion;
• Ada.Numbers.Constants which contains the constants used in conversions;
• Ada.Numbers.Utilities which contains some useful methods such as the number of digits and the category of the number.

Ada.Numbers.Settings

Used to set the parameters of the converters. Available parameters are:

• Language;
• Scale.

To set the language, it is done as follows:

Settings.Language = Settings.Parameters.Languages.En //Now, converters will use English

To set the scale, it is done as follows:

Settings.Scale = Settings.Parameters.Scales.Short //Now, converters will use Short Scale

To learn more about scales, read this.

The Settings are global, meaning that once they are set, every operation is affected, so, in order to have a different behavior, the Settings must be explicitly set. Per default, Language is Portuguese and the Scale is Long.

Ada.Numbers.Converters

For string, the method is .ToNumber().

Examples:

var number = "vinte e dois";
number.ToNumber() // > "22"

Settings.Language = Settings.Parameters.Languages.En //Now, converters will use English
number = "twenty-two";
number.ToNumber(); // > "22"

Check the method documentation for more details.

For numerical types (long, int, byte, decimal, double and float), the method is .ToWords().

var number = 22;
number.ToWords() // > "Vinte e Dois"

Settings.Language = Settings.Parameters.Languages.En //Now, converters will use English
var number = 22;
number.ToWords() // > "Twenty-two"

Check the method documentation for more details.
