dtype

Return a data type from a string representing the data type.

Mostly useful for using with ndarray where you would like instantiate a typed array of the same array.dtype.

See ndarray-dtype if you need to support Buffer and other ndarray types.

Fork modifications

  • Added support for single letter strings (D, F, J, I, see table below)

example

var dtype = require('dtype')
var ndarray = require('ndarray')

var arr = ndarray(new Int8Array(32))

// some time later

var newarr = ndarray(new (dtype(arr.dtype)))

API

dtype(string) will return the following data types based on the strings given:

Data type String
Int8Array "int8"
Int16Array "int16" or "i"
Int32Array "int32" or "l"
Uint8Array "uint8"
Uint16Array "uint16"
Uint32Array "uint32"
Float32Array "float32" or "f"
Float64Array "float64" or "d"
Array "array"
Uint8ClampedArray "uint8_clamped"

Returns undefined if the type isn't recognized.

install

With npm do:

npm install @talenfisher/dtype

Use browserify to require('dtype').
