Good call all changed thanks

Hey @mojodojodev I think you did a find and replace over all the files and that's created some mistakes like:

So we use Int32 instead of Int32, similarly using Float32 instead of Float32. Closes Issue #152.

I think it needs to be done more selectively like in the the guides only, or something like that.

Whoops! I think that was the only one (mentioning old syntax with new change), did a quick run through and looks all clear. Thanks again!

Ok that's good then! Cheers.
