Creates a zero-filled array having a specified length.

@param {NonNegativeInteger} length - array length
@param {string} [dtype="float64"] - data type
@throws {TypeError} first argument must be a nonnegative integer
@throws {TypeError} second argument must be a recognized data type
@returns {(TypedArray|Array|ComplexArray)} array or typed array

@example
var arr = zeros( 2 );
// returns <Float64Array>[ 0.0, 0.0 ]

@example
var arr = zeros( 2, 'float32' );
// returns <Float32Array>[ 0.0, 0.0 ]
