The following one-line program produces a strange error message.
FindMinimum[(2.3-FindMinimum[Sin[x y],{x,2}][[2,1,2]])^2,{y,1}][[2,1,2]]
The error message is
FindMinimum::nnum: The function value Sin[2. y] is not a number at {x} =
{2.}.
Eventually, the correct output (2.05 or thereabouts) is given, but how can
this code be re-written so as not to produce the error message (barring the
obvious hack of Off[FindMinimum::nnum])?
