Usage

var ns = require( '@omegion1npm/corrupti-autem-reiciendis' );

ns

Arrays.

var o = ns;
// returns {...}

The namespace exports the following array constructors:

• ArrayBuffer( size ): constructor which returns an object used to represent a generic, fixed-length raw binary data buffer.
• Float32Array(): typed array constructor which returns a typed array representing an array of single-precision floating-point numbers in the platform byte order.
• Float64Array(): typed array constructor which returns a typed array representing an array of double-precision floating-point numbers in the platform byte order.
• Int16Array(): typed array constructor which returns a typed array representing an array of twos-complement 16-bit signed integers in the platform byte order.
• Int32Array(): typed array constructor which returns a typed array representing an array of twos-complement 32-bit signed integers in the platform byte order.
• Int8Array(): typed array constructor which returns a typed array representing an array of twos-complement 8-bit signed integers in the platform byte order.
• SharedArrayBuffer( size ): constructor returning an object used to represent a generic, fixed-length raw binary data buffer which can be used to create views of shared memory.
• Uint16Array(): typed array constructor which returns a typed array representing an array of 16-bit unsigned integers in the platform byte order.
• Uint32Array(): typed array constructor which returns a typed array representing an array of 32-bit unsigned integers in the platform byte order.
• Uint8Array(): typed array constructor which returns a typed array representing an array of 8-bit unsigned integers in the platform byte order.
• Uint8ClampedArray(): typed array constructor which returns a typed array representing an array of 8-bit unsigned integers in the platform byte order clamped to 0-255.

var arr = new ns.Int32Array( 5 );
// returns <Int32Array>[ 0, 0, 0, 0, 0 ]

Alternatively, use the typedarray function to create a typed array of a given data type:

• typedarray(): create a typed array.

var arr1 = ns.typedarray( 5 );
// returns <Float64Array>[ 0.0, 0.0, 0.0, 0.0, 0.0 ]

var arr2 = ns.typedarray( 5, 'uint8' );
// returns <Uint8Array>[ 0, 0, 0, 0, 0 ]

The namespace contains functions to create arrays pre-filled with spaced values:

• datespace( start, stop[, length][, opts] ): generate an array of linearly spaced dates.
• incrspace( start, stop[, increment] ): generate a linearly spaced numeric array using a provided increment.
• linspace( start, stop, length[, options] ): generate a linearly spaced array over a specified interval.
• logspace( a, b[, length] ): generate a logarithmically spaced numeric array.

You can use the following functions to retrieve a list of available data types:

• dtypes( [kind] ): list of array data types.
• complexarrayDataTypes(): list of complex typed array data types.
• typedarrayDataTypes(): list of typed array data types.
• floatarrayDataTypes(): list of typed array floating-point data types.

• realarrayFloatDataTypes(): list of typed array real-valued floating-point data types.
• intarraySignedDataTypes(): list of typed array signed integer data types.
• intarrayUnsignedDataTypes(): list of typed array unsigned integer data types.

Furthermore, the namespace contains utility functions to retrieve a given constructor:

• ctors( dtype ): array constructors.
• ArrayIndex( x[, options] ): array index constructor.
• complexarrayCtors( dtype ): complex typed array constructors.
• typedarrayCtors( dtype ): typed array constructors.

• realarrayFloatCtors( dtype ): real-valued floating-point typed array constructors.
• intarraySignedCtors( dtype ): signed integer typed array constructors.
• intarrayUnsignedCtors( dtype ): unsigned integer typed array constructors.

var ctor = ns.typedarrayCtors( 'float64' );
// returns <Function>

ctor = ns.typedarrayCtors( 'int' );
// returns null
