[Numpy-discussion] Custom floating point representation to IEEE 754 double

2014-02-25 Thread Daniele Nicolodi
Hello, I'm dealing with an instrument that transfers numerical values through an RS232 port in a custom (?) floating point representation (56 bits, 4 bits exponent and 52 bits significand). Of course I need to convert this format to a standard IEEE 754 double to be able to do anything useful with
