/**
* Rounds each element in a double-precision floating-point strided array `x` toward zero and assigns the results to elements in a double-precision floating-point strided array `y`.
*
* @param {NonNegativeInteger} N - number of indexed elements
* @param {Float64Array} x - input array
* @param {integer} strideX - `x` stride length
* @param {NonNegativeInteger} offsetX - starting `x` index
* @param {Float64Array} y - destination array
* @param {integer} strideY - `y` stride length
* @param {NonNegativeInteger} offsetY - starting `y` index
* @returns {Float64Array} `y`
*
* @example
* var Float64Array = require( '@stdlib/array/float64' );
*
* var x = new Float64Array( [ 1.1, 2.5, -3.5, 4.0, -5.9 ] );
* var y = new Float64Array( [ 0.0, 0.0, 0.0, 0.0, 0.0 ] );
*
* dtrunc( x.length, x, 1, 0, y, 1, 0 );
