dtype

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.

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"
Int32Array	"int32"
Uint8Array	"uint8"
Uint16Array	"uint16"
Uint32Array	"uint32"
Float32Array	"float32"
Float64Array	"float64"
Array	"array"
Uint8ClampedArray	"uint8_clamped"

Returns undefined if the type isn't recognized.

install

With npm do:

npm install dtype

Use browserify to require('dtype').
