+1.  I don't know anything about these functions per se, but am persuaded by Edward's case that they are standard and expected by numerical analysts.  My only reservation is that GHC.Float is too implementation-specific a location for them.  If these functions are important, they are important enough to make standard.  Let's have them in module Numeric, or Numeric.Floating, or whatever.
