Why does numpy warn me about overflow in scalar subtract if it happens with an np.uint8-typed int, but not when the same value is part of a 0-d array?
These two lines:
res0 = np.array(np.uint8(40))-80 # np.uint8(216), no warning
res1 = np.uint8(40)-80 # np.uint8(216), warning
seem to work identically. Both res0 and res1 will be np.uint8(216). np....

Why does np.vectorize(function) avoid an integer overflow which the function itself encounters when not wrapped in np.vectorize?

1.0 * (np.array([np.uint8(40)])-80)
results in array([216.]). So, it is also not surprising that:
import numpy as np
C = 1.0
def f(x):
