title: How to find epsilon, min and max constants for CUDA?
body: <p>I'm looking for the values of epsilon (the smallest step between two numbers), min (the smallest magnitude) and max (the greatest magnitude) for CUDA devices.</p>
  
  <p>I.E the equivalents to FLT_EPSILON (DBL_EPSILON), FLT_MIN (DBL_MIN) and FLT_MAX (DBL_MAX) defined in <code>&lt;float.h&gt;</code> in gcc compilers.</p>
  
  <p>Are there constants in some CUDA include file?
  Any manual explaining them? Any way to write a kernel to compute them?</p>
  
  <p>Thanks in advance.</p>
