Convert Number to Binary Coded Decimal using Modulus and Division Approach
In PHP, you can convert a number to Binary Coded Decimal (BCD) using string manipulation by first converting the number to a string, then splitting the string into individual digits, and finally converting each digit to its corresponding 4-bit binary representation.
Example: Implementation to convert numbers to binary coded decimal.
PHP
<?php function decimalToBCD($number) { $bcd = ""; while ($number > 0) { $digit = $number % 10; $bcd = str_pad(decbin($digit), 4, "0", STR_PAD_LEFT) . $bcd; $number = (int) ($number / 10); } return $bcd; } // Driver code $number = 123; $bcd = decimalToBCD($number); echo "BCD of $number is $bcd"; ?> |
Output
BCD of 123 is 000100100011
Explanation:
- The decimalToBCD( ) function takes a decimal number as input.
- It extracts each digit of the number using the modulo operator `%` and converts it to a 4-bit binary string using decbin( ).
- The str_pad( ) function is used to ensure that each binary representation is 4 characters long by padding with zeros on the left if necessary.
- The binary strings are concatenated to form the BCD representation.
- The loop continues until all digits of the number have been processed.
Convert Number to Binary Coded Decimal in PHP
Binary Coded Decimal (BCD) is a class of binary encodings of decimal numbers where each decimal digit is represented by a fixed number of binary digits, usually four or eight. This article will explore how to convert a decimal number to its BCD representation in PHP with multiple approaches.
