[cvs-nhc98] cvs commit: nhc98/src/prelude/Prelude Floating_Double.hs Floating_Float.hs

malcolm 2004/10/05 11:54:17 PDT Modified files: src/prelude/Prelude Floating_Double.hs Floating_Float.hs Log: The default definition of (**) in class Floating loses precision. In particular, many calculations incorrectly have result NaN. The fix is to use the C library function pow() instead, and hook it into nhc98 as a new bytecode instruction.
