Mutual online converter of BCD and decimal numbers

The BCD code (Binary-Coded Decimal) is also called the binary code decimal or binary code. Use a 4-bit binary number to represent the 10 digits from 0 to 9 in a 1-digit decimal number. Is a binary digitally encoded form with a binary coded decimal code. This encoding form of the BCD code utilizes four bits to store a decimal number, enabling fast conversion between binary and decimal. This coding technique is most commonly used in the design of accounting systems because accounting systems often require accurate calculations of very long strings of numbers. Compared with the general floating-point notation method, the BCD code can save the accuracy of the value and eliminate the time taken for the computer to perform floating-point operations. In addition, BCD coding is also very common for other calculations that require high precision.
