iirc, you have to swap bytes around. the code on this page might be helpful: http://www.octave.org/octave-lists/archive/octave-sources.2004/msg00033.html > The problem would be there if you had, say, floats in old IBM 360/370 > formats, or Cray's original formats, or the like... here's a IBM 360 converter (at least that's what I think it is; the code is taken from a PIL format converter for a format that uses "IBM floats"): def ibm_f32s(c): a = ord(c[0]) & 127 b = ord(c[3]) + (ord(c[2])<<8) + (ord(c[1])<<16) v = pow(2.0, -24) * b * pow(16.0, a-64) if ord(c[0]) > 127: return -v return v many floating point formats are trivial variations on this theme. </F> -- http://mail.python.org/mailman/listinfo/python-list
