constexpr auto minmax
Computes the minimum and maximum of its arguments.

EVE Main Namespace.

Parameters

Return value

  1. A kumi::tuple containing the value of the minimum and the maximum of the arguments.
  2. Equivalent to the call on the elements of the tuple.
  3. The operation is performed conditionnaly
  4. Equivalent to {min[o], max[o]} where o is one of these two options.
Note
  • If any element of the inputs is a Nan, the corresponding output element is system-dependent.

Semantic Modifiers

  • Masked Call

    The call eve::minmax[mask](x, ...) provides a masked version of minmax which is equivalent to if_else(mask, minmax(x, ...), x)
