Usage

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

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)
• 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

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 ]

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 ]
