Subject: Bit twiddling in Java
I need to convert some IBM formatted floating point data from
a binary file so I can read into VisAd. This uses a different
number of bits for the exponent and mantissa than is used by
the IEEE representation. Can anyone point me at code or a
tutorial on bit-twiddling in Java?
