numericType

Declaration

var numericType: Unicode.NumericType? { get }

Discussion

For scalars that represent a number, numericType is the numeric type of the scalar. For all other scalars, this property is nil.

let scalars: [Unicode.Scalar] = ["4", "④", "⅕", "X"]
for scalar in scalars {
    print(scalar, "-->", scalar.properties.numericType)
}
// 4 --> Optional(Swift.Unicode.NumericType.decimal)
// ④ --> Optional(Swift.Unicode.NumericType.digit)
// ⅕ --> Optional(Swift.Unicode.NumericType.numeric)
// X --> nil

This property corresponds to the “Numeric_Type” property in the Unicode Standard.
