Is there a ufunc for rounding away from zero? Or do I need to do
x2 = sign(x) * ceil(abs(x))
whenever I want to round away from zero? Maybe the following is better?
x_ceil = ceil(x)
x_floor = floor(x)
x2 = where(x >= 0, x_ceil, x_floor)
Python's round function goes away from zero, so I am looking for the NumPy
equivalent (and using vectorize() seems undesirable). In this sense, it
seems that having a ufunc for this type of rounding could be helpful.
Aside: Is there interest in a more general around() that allows users to
specify alternative tie-breaking rules, with the default staying 'round
half to nearest even'? [1]
Also, what is the difference between NumPy's fix() and trunc() functions?
It seems like they achieve the same goal. trunc() was added in 1.3.0. So is
fix() just legacy?
