/**
* Tests if two arguments are both Float64Arrays and contain respective elements which are approximately the same value within a specified number of ULPs (units in the last place).
*
* ## Notes
*
* - In contrast to the strict equality operator `===`, `-0` and `+0` are distinguishable and `NaNs` are the same.
*
* @param {*} v1 - first value
* @param {*} v2 - second value
* @param {NonNegativeInteger} maxULP - maximum allowed ULP difference
* @returns {boolean} boolean result
*
* @example
* var Float64Array = require( '@stdlib/array/float64' );
*
* var x = new Float64Array( [ 1.0, 2.0, 3.0 ] );
* var y = new Float64Array( [ 1.0, 2.0, 3.0 ] );
*
* var out = isAlmostSameValueFloat64Array( x, y, 0 );
* // returns true
