I want to truncate the float values within the numpy array, for .e.g.

```
2.34341232 --> 2.34 

```

I read the post [truncate floating point](https://stackoverflow.com/questions/783897/truncating-floats-in-python) but its for one float. I don't want to run a loop on the numpy array, it will be quite expensive. Is there any inbuilt method within numpy which can do this easily? I do need output as a float not string.
