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.
