Odd behavior when Java converts int to byte?
...
132 in digits (base 10) is 1000_0100 in bits (base 2) and Java stores int in 32 bits:
0000_0000_0000_0000_0000_0000_1000_0100
Algorithm for int-to-byte is left-truncate; Algorithm for System.out.println is two's-complement (Two's-complement is if leftmos...

How to use filter, map, and reduce in Python 3
...
@Breezer actually i**3 will call i.__pow__(3) and i*i*i i.__mul__(i).__mul__(i) (or something like that). With ints it doesn't matter but with numpy numbers/custom classes it might even produce different results.
