## What is Binary Coded Decimal System?

In computing and electronic systems, binary-coded decimal (BCD) is a class of binary encodings of decimal numbers where each digit is represented by a fixed number of bits, usually four or eight. Sometimes, special bit patterns are used for a sign or other indications (e.g. error or overflow).

## What is BCD format?

Binary coded decimal (BCD) is a system of writing numerals that assigns a four-digit binary code to each digit 0 through 9 in a decimal (base-10) numeral. The four-bit BCD code for any particular single base-10 digit is its representation in binary notation, as follows: 0 = 0000. 1 = 0001. 2 = 0010.

**What is the use of BCD code?**

Binary-coded Decimal or BCD is a way of representing a decimal number as a string of bits suitable for use in electronic systems. Rather than converting the whole number into binary, BCD splits the number up into its digits and converts each digit to 4-bit binary.

**How do you write BCD code?**

In BCD code, each digit of the decimal number is represented as its equivalent binary number….Example 1: (11110) 2.

Binary Code | Decimal Number | BCD Code |
---|---|---|

0 0 0 1 | 1 | 0 : 0 0 0 1 |

0 0 1 0 | 2 | 0 : 0 0 1 0 |

0 0 1 1 | 3 | 0 : 0 0 1 1 |

0 1 0 0 | 4 | 0 : 0 1 0 0 |

### How do you do BCD?

In BCD code, each digit of the decimal number is represented as its equivalent binary number….Example 1: (11110) 2.

Binary Code | Decimal Number | BCD Code |
---|---|---|

0 0 1 0 | 2 | 0 : 0 0 1 0 |

0 0 1 1 | 3 | 0 : 0 0 1 1 |

0 1 0 0 | 4 | 0 : 0 1 0 0 |

0 1 0 1 | 5 | 0 : 0 1 0 1 |

### Why BCD codes are used?

The BCD system offers relative ease of conversion between machine-readable and human-readable numerals. In this article, we will learn about BCD, Binary Coded Decimal, which offers relative ease of conversion between machine-readable and human-readable numerals.

**How do I convert BCD?**

There are the following steps to convert the binary number to BCD: First, we will convert the binary number into decimal. We will convert the decimal number into BCD….Example 1: (11110) 2.

Binary Code | Decimal Number | BCD Code |
---|---|---|

A B C D | B4 :B3B2B1B0 | |

0 0 0 0 | 0 | 0 : 0 0 0 0 |

0 0 0 1 | 1 | 0 : 0 0 0 1 |

0 0 1 0 | 2 | 0 : 0 0 1 0 |
