Typed Arrays
Create a typed array.
Installation
npm install @devtea2026/illo-laborum-doloremque-libero
Alternatively,
- To load the package in a website via a
script
tag without installation and bundlers, use the ES Module available on theesm
branch (see README). - If you are using Deno, visit the
deno
branch (see README for usage intructions). - For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the
umd
branch (see README).
The branches.md file summarizes the available branches and displays a diagram illustrating their relationships.
To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.
Usage
var typedarray = require( '@devtea2026/illo-laborum-doloremque-libero' );
typedarray( [dtype] )
Creates a typed array having a specified data type dtype
.
var arr = typedarray();
// returns <Float64Array>
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 numberscomplex64
: single-precision complex floating-point numbersint32
: 32-bit two's complement signed integersuint32
: 32-bit unsigned integersint16
: 16-bit two's complement signed integersuint16
: 16-bit unsigned integersint8
: 8-bit two's complement signed integersuint8
: 8-bit unsigned integersuint8c
: 8-bit unsigned integers clamped to0-255
By default, the output typed array data type is float64
. To specify an alternative data type, provide a dtype
argument.
var arr = typedarray( 'int32' );
// returns <Int32Array>
typedarray( length[, dtype] )
Returns a typed array having a specified length
.
var arr1 = typedarray( 5 );
// returns <Float64Array>[ 0.0, 0.0, 0.0, 0.0, 0.0 ]
var arr2 = typedarray( 5, 'uint8' );
// returns <Uint8Array>[ 0, 0, 0, 0, 0 ]
typedarray( typedarray[, dtype] )
Creates a typed array from another typed array.
var arr1 = typedarray( [ 5.0, -3.0, 2.0 ] );
// returns <Float64Array>[ 5.0, -3.0, 2.0 ]
var arr2 = typedarray( arr1 );
// returns <Float64Array>[ 5.0, -3.0, 2.0 ]
var arr3 = typedarray( arr1, 'int32' );
// returns <Int32Array>[ 5, -3, 2 ]
typedarray( obj[, dtype] )
Creates a typed array from an array-like object or iterable.
var arr1 = typedarray( [ 0.5, 0.5, 0.5 ] );
// returns <Float64Array>[ 0.5, 0.5, 0.5 ]
var arr2 = typedarray( [ 0.5, 0.5, 0.5 ], 'float32' );
// returns <Float32Array>[ 0.5, 0.5, 0.5 ]
If dtype
is complex number data type and an array-like object contains interleaved real and imaginary components, the array-like object must have a length which is a multiple of two.
typedarray( buffer[, byteOffset[, length]][, dtype] )
Returns a typed array view of an ArrayBuffer
.
var ArrayBuffer = require( '@stdlib/array-buffer' );
var buf = new ArrayBuffer( 32 );
var arr1 = typedarray( buf );
// returns <Float64Array>[ 0.0, 0.0, 0.0, 0.0 ]
var arr2 = typedarray( buf, 'float32' );
// returns <Float32Array>[ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ]
var arr3 = typedarray( buf, 16 );
// returns <Float64Array>[ 0.0, 0.0 ]
var arr4 = typedarray( buf, 16, 'float32' );
// returns <Float32Array>[ 0.0, 0.0, 0.0, 0.0 ]
var arr5 = typedarray( buf, 16, 1 );
// returns <Float64Array>[ 0.0 ]
var arr6 = typedarray( buf, 10, 4, 'int16' );
// returns <Int16Array>[ 0, 0, 0, 0 ]
Notes
- When providing a complex number array, if
dtype
is unspecified or the specified data type is not a complex number data type, the returned array contains interleaved real and imaginary components.
Examples
var randu = require( '@stdlib/random-base-randu' );
var typedarray = require( '@devtea2026/illo-laborum-doloremque-libero' );
var arr = typedarray( 100, 'float64' );
var i;
for ( i = 0; i < arr.length; i++ ) {
arr[ i ] = randu() * 100.0;
}
console.log( arr );
