Added Float32/64 Typed array types
Added Float32/64 Typed array types

Seems like someone forgot to re-export Float32Array and  Float64Array in JavaScript.TypedArray from JavaScript.TypedArray.Internal.Types.
Also I would like to have (TypedArray a => JSRef -> a) interface for my WebGL things: some of the webGL methods return typed arrays of arbitrary type - https://developer.mozilla.org/en-US/docs/Web/API/ArrayBufferView
