warp.copysign
=============

.. function:: warp._src.lang.copysign(x: Float, y: Float) -> Float

   .. hlist::
      :columns: 8

      * Kernel
      * Differentiable

   Return a value with the magnitude of ``x`` and the sign of ``y``.
   
   For example, ``wp.copysign(3.0, -1.0)`` returns ``-3.0`` and
   ``wp.copysign(-3.0, 1.0)`` returns ``3.0``. Useful for forcing a
   specific sign on a result whose signed-zero behavior is otherwise
   implementation-defined (e.g. ``wp.min(-0.0, +0.0)``).
