full

Create a filled array having a specified length.

Installation

npm install @stdlib/array-full

Alternatively,

• To load the package in a website via a script tag without installation and bundlers, use the ES Module available on the esm branch.
• If you are using Deno, visit the deno branch.
• For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the umd branch.

The branches.md file summarizes the available branches and displays a diagram illustrating their relationships.

Usage

var full = require( '@stdlib/array-full' );

full( length, value[, dtype] )

Creates a filled array having a specified length.

var arr = full( 2, 1.0 );
// returns <Float64Array>[ 1.0, 1.0 ]

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 = full( 2, 1, 'int32' );
// returns <Int32Array>[ 1, 1 ]

Examples

var dtypes = require( '@stdlib/array-typed-real-dtypes' );
var full = require( '@stdlib/array-full' );

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

// Generate filled arrays...
var arr;
var i;
for ( i = 0; i < dt.length; i++ ) {
    arr = full( 5, i+1, dt[ i ] );
    console.log( arr );
}
