title: Java equivalents of DBL_MIN_10_EXP, FLT_RADIX and others from float.h
body: <p>I'm working on adding <a href="http://hg.python.org/cpython/file/ab157c169f6e/Objects/floatobject.c#l76" rel="nofollow">sys.float_info</a> to Jython. It has several attributes from float.h.
  I'm trying to find the Java equivalent for <code>DBL_MIN_10_EXP</code>, <code>DBL_MANT_DIG</code>, <code>FLT_RADIX</code> and <code>FLT_ROUNDS</code>.</p>
  
  <p>Any ideas?</p>
  
  <p>I <em>think</em> I have the rest of the attributes, some from java.lang.Double and the rest from looking at <code>Num</code> class in the ssj library.</p>
