Binary conversion seems simple, but when dealing with network protocols, hardware interfaces, or low-level file formats, critical mistakes can be introduced. Avoiding these common errors ensures data integrity across different systems.
Misinterpreting the byte order of binary data. Systems use either *Big-Endian* (most significant byte first) or *Little-Endian* (least significant byte first). Reading data intended for one system on a system using the opposite endianness will corrupt the data.
Always verify the expected endianness of the data source (e.g., network protocols are often Big-Endian) before performing multi-byte conversions.
Treating signed numbers (which use the most significant bit to denote positive/negative) as unsigned numbers (which use all bits for magnitude). This leads to massive decimal errors.
Explicitly select the appropriate setting in the converter tool (e.g., 'Signed 2's Complement' vs. 'Unsigned') before conversion.
Converting text to binary assuming $\text{ASCII}$ encoding when the source text uses $\text{UTF-8}$ (or vice versa). $\text{UTF-8}$ uses variable byte lengths for characters, while $\text{ASCII}$ uses $1 \text{ byte}$ per character.
Confirm the source document's encoding. If the document contains any special characters, $\text{UTF-8}$ must be selected for accurate conversion.
Converting a large number that requires 16 bits into an 8-bit register, causing a data overflow and loss of the most significant bits.
Use the binary converter to determine the minimum bit width required for your largest number and allocate memory accordingly.
