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

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):
