{{alias}}( [out,] x )
    Decomposes a double-precision floating-point number into integral and
    fractional parts, each having the same type and sign as the input value.

    Parameters
    ----------
    out: Array|TypedArray|Object (optional)
        Output array.

    x: number
        Input value.

    Returns
    -------
    parts: Array|TypedArray|Object
        Integral and fractional parts.

    Examples
    --------
    > var parts = {{alias}}( 3.14 )
    [ 3.0, 0.14000000000000012 ]
    > parts = {{alias}}( 3.14 )
    [ 3.0, 0.14000000000000012 ]
    > parts = {{alias}}( +0.0 )
    [ +0.0, +0.0 ]
    > parts = {{alias}}( -0.0 )
    [ -0.0, -0.0 ]
    > parts = {{alias}}( {{alias:@stdlib/constants/float64/pinf}} )
    [ Infinity, +0.0 ]
    > parts = {{alias}}( {{alias:@stdlib/constants/float64/ninf}} )
    [ -Infinity, -0.0 ]
    > parts = {{alias}}( NaN )
    [ NaN, NaN ]

    // Provide an output array:
    > var out = new {{alias:@stdlib/array/float64}}( 2 );
    > parts = {{alias}}( out, 3.14 )
    <Float64Array>[ 3.0, 0.14000000000000012 ]
    > var bool = ( parts === out )
    true
