{{alias}}( N, x, strideX, y, strideY ) Rounds each element in a double-precision floating-point strided array `x` toward positive infinity and assigns the results to elements in a double- precision floating-point strided array `y`. The `N` and `stride` parameters determine which elements in `x` and `y` are accessed at runtime. Indexing is relative to the first index. To introduce an offset, use typed array views. Parameters ---------- N: integer Number of indexed elements. x: Float64Array Input array. strideX: integer Index increment for `x`. y: Float64Array Destination array. strideY: integer Index increment for `y`. Returns ------- y: Float64Array Input array `y`. Examples -------- // Standard usage: > var x = new {{alias:@stdlib/array/float64}}( [ 1.1, 2.5, -3.5, 4.0 ] ); > var y = new {{alias:@stdlib/array/float64}}( [ 0.0, 0.0, 0.0, 0.0 ] ); > {{alias}}( x.length, x, 1, y, 1 ) [ 2.0, 3.0, -3.0, 4.0 ] // Using `N` and `stride` parameters: > var N = {{alias:@stdlib/math/base/special/floor}}( x.length / 2 ); > y = new {{alias:@stdlib/array/float64}}( [ 0.0, 0.0, 0.0, 0.0 ] ); > {{alias}}( N, x, 2, y, -1 ) [ -3.0, 2.0, 0.0, 0.0 ] // Using view offsets: > var x0 = new {{alias:@stdlib/array/float64}}( [ 1.1, 2.5, -3.5, 4.0 ] ); > var y0 = new {{alias:@stdlib/array/float64}}( [ 0.0, 0.0, 0.0, 0.0 ] ); > var x1 = new {{alias:@stdlib/array/float64}}( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); > var y1 = new {{alias:@stdlib/array/float64}}( y0.buffer, y0.BYTES_PER_ELEMENT*2 ); > N = {{alias:@stdlib/math/base/special/floor}}( x0.length / 2 ); > {{alias}}( N, x1, -2, y1, 1 ) [ 4.0, 3.0 ] > y0 [ 0.0, 0.0, 4.0, 3.0 ] {{alias}}.ndarray( N, x, strideX, offsetX, y, strideY, offsetY ) Rounds each element in a double-precision floating-point strided array `x` toward positive infinity and assigns the results to elements in a double- precision floating-point strided array `y` using alternative indexing semantics. While typed array views mandate a view offset based on the underlying buffer, the `offsetX` and `offsetY` parameters support indexing semantics based on starting indices. Parameters ---------- N: integer Number of indexed elements. x: Float64Array Input array. strideX: integer Index increment for `x`. offsetX: integer Starting index for `x`. y: Float64Array Destination array. strideY: integer Index increment for `y`. offsetY: integer Starting index for `y`. Returns ------- y: Float64Array Input array `y`. Examples -------- // Standard usage: > var x = new {{alias:@stdlib/array/float64}}( [ 1.1, 2.5, -3.5, 4.0 ] ); > var y = new {{alias:@stdlib/array/float64}}( [ 0.0, 0.0, 0.0, 0.0 ] ); > {{alias}}.ndarray( x.length, x, 1, 0, y, 1, 0 ) [ 2.0, 3.0, -3.0, 4.0 ] // Advanced indexing: > x = new {{alias:@stdlib/array/float64}}( [ 1.1, 2.5, -3.5, 4.0 ] ); > y = new {{alias:@stdlib/array/float64}}( [ 0.0, 0.0, 0.0, 0.0 ] ); > var N = {{alias:@stdlib/math/base/special/floor}}( x.length / 2 ); > {{alias}}.ndarray( N, x, 2, 1, y, -1, y.length-1 ) [ 0.0, 0.0, 4.0, 3.0 ] See Also --------
