Class Bcd

Namespace

Yubico.Core.Buffers

Assembly

Yubico.Core.dll

Class for encoding and decoding bytes into BCD (binary coded decimal) format.

public class Bcd : Base16, ITextEncoding

Inheritance

object

Base16

Bcd

Implements

ITextEncoding

Inherited Members

Base16.DefaultLowerCase

Base16.Encode(ReadOnlySpan<byte>, Span<char>)

Base16.Encode(ReadOnlySpan<byte>)

Base16.Decode(ReadOnlySpan<char>, Span<byte>)

Base16.Decode(string)

Remarks

BCD is a way to represent decimal data in a format that is both easy to parse and easily human-readable. Each four bits is one decimal digit. The obvious disadvantage is that the data is far less dense. Each byte can only contain less than seven full bits of data.

Properties

CharacterSet

The set of characters that correspond to numbers 0 - 16.

protected override Span<char> CharacterSet { get; }

Property Value

Span<char>
