bcd

binary coded decimals

Installation

npm install bcd

Usage

• bcd.encode(num) — encode given number into a buffer with a minimal length that fits the result;
• bcd.encode(num, length) — encode given number into a buffer with a given length. If length is more than needed, the result is aligned at the right side of the buffer and the rest is filled with zeroes. If length is less then needed, the result is truncated from the left side;
• bcd.encode(num, buffer) — encode givento number into a given buffer. The above rules regarding length are applied.
• bcd.decode(buffer) — decode given buffer into a number. If the buffer is not a valid BCD, this method throws.
