Convert System::Byte[] to a Hex string If this is your first visit, be sure to check out the FAQ by clicking the link above. In conclusion - yes, there are cases when you can use a simple encoding like win-1252 to decode an arbitrary byte array (for example if you want to look for a specific raw "string" within a file) but in most cases, especially if this data is to be transferred somewhere as a string - use Base64 or Hex encoding!. Both the "I" specifier and the endianness of the string->int conversion are dependent on your particular Python implementation. Alternately, I have a byte array (in some known encoding) and I want to convert it into a Java String. Python 2: this string literal is called a "str" object but its stored as bytes. Decimals, Floats, and Floating Point Arithmetic¶ Floating point numbers like 12. The QByteArray class provides an array of bytes.
