Returns the minimum and maximum values.

@param {number} [x] - first number
@param {number} [y] - second number
@param {...number} [args] - numbers
@returns {Array<number>} minimum and maximum values

@example
var v = minmaxn( 3.14, 4.2 );
// returns [ 3.14, 4.2 ]

@example
var v = minmaxn( 3.14, NaN );
// returns [ NaN, NaN ]

@example
var v = minmaxn( +0.0, -0.0 );
// returns [ -0.0, 0.0 ]
