Java should incorporate the following methods into java.lang.Math:

      copySign(x,y) returns x with the sign of y.
      scalb(y,n) returns y * 2n for integers n without
                     explicitly computing 2n.
      nextAfter(x,y) returns the next representable neighbor of x in the
                     direction towards y.
      unordered(x,y) Returns true is one of its arguments is unordered
                     with respect to the other.
                     This occurs when at least one is a NaN.
      fpClass(x) Returns an integer that indicates which of the
                     nine "kinds" of IEEE floating-point numbers x is.
      logb(x) Returns the unbiased exponent of x.

These descriptions are copied from:

It also says there that IEEE 754 recommends these methods.
