Typography.NumeralAlignment Attached Property
Gets or sets a FontNumeralAlignment enumerated value that indicates the alignment of widths when using numerals.
Assembly: System.Windows (in System.Windows.dll)
This property gets or sets a value on the object that owns a Typography property, which is the only way to access a Typography class instance. In addition, this property supports an attached property usage so that it can be set on text-containing objects in XAML.
OpenType fonts support a proportional and tabular figure feature to control the alignment of widths when using numerals. Proportional figures treat each numeral as having a different width—"1" is narrower than "5". Tabular figures are treated as equal-width numerals so that they align vertically, which increases the readability of financial type information.
