zeros

Create a zero-filled array having a specified length.

Usage

var zeros = require( '@stdlib/array/zeros' );

zeros( length[, dtype] )

Creates a zero-filled array having a specified length.

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

The function recognizes the following data types:

float64: double-precision floating-point numbers (IEEE 754)
float32: single-precision floating-point numbers (IEEE 754)
complex128: double-precision complex floating-point numbers
complex64: single-precision complex floating-point numbers
int32: 32-bit two's complement signed integers
uint32: 32-bit unsigned integers
int16: 16-bit two's complement signed integers
uint16: 16-bit unsigned integers
int8: 8-bit two's complement signed integers
uint8: 8-bit unsigned integers
uint8c: 8-bit unsigned integers clamped to 0-255
generic: generic JavaScript values

By default, the output array data type is float64 (i.e., a typed array). To specify an alternative data type, provide a dtype argument.

var arr = zeros( 2, 'int32' );
// returns <Int32Array>[ 0, 0 ]

Examples

var dtypes = require( '@stdlib/array/dtypes' );
var zeros = require( '@stdlib/array/zeros' );

// Get a list of array data types:
var dt = dtypes();

// Generate zero-filled arrays...
var arr;
var i;
for ( i = 0; i < dt.length; i++ ) {
    arr = zeros( 4, dt[ i ] );
    console.log( arr );
