nearfloat — get previous or next floating-point number
xnear = nearfloat(dir, x)
string ("succ" or "pred")
real scalar, vector or matrix
real scalar, vector or matrix
This function computes, in the element wise meaning, the corresponding neighbours
of the elements of x
(in the underlying floating point set, see number_properties),
the successors if dir = "succ"
and the predecessors if
dir = "pred"
