The 32-bit question (or 16-bit, which I didn't ask about) is different from the int -> long int behavior. These "big number" libraries are useful because the libraries adjust their size to accommodate the data value given. Card trick: guessing the suit if you see the remaining three cards (important is that you can't move or turn the cards).

It's so the programmer can choose a storage type that minimizes wasted space while still giving good execution speed. A Python integer is represented as either of 32-bit or 64-bit signed integer type that is platform-specific, without considering it as an Python object.As indicated in the documentation, whether it is 32-bit or 64-bit can be revealed by checking sys.maxsize (or sys.maxint on older CPython implementations such as 2.4), the value of # Find size of int import sys sys.getsizeof( int() ) # prints 24 sys.getsizeof(0) # prints 24 sys.getsizeof(1) # prints 28 sys.getsizeof(-2) # prints 28 sys.getsizeof(2* 10**307) # prints 164 Bits are binary, meaning they may only be a zero or a one. >>> dt = np. numba.types.uint. Binary digits (bits) are the smallest unit of data stored in a computer. Given an positive integer and size of bits, reverse all bits of it and return the number with reversed bits.Examples: Input : n = 1, bitSize=32 Output : 2147483648 On a machine with size of bit as 32.

It's important to choose an appropriate size that doesn't waste excessive storage space but can still hold all possible values the variable can take on both now and into the future. They are either 0/1, on/off, or yes/no. There is no significant speed difference because the modern processors can handle the size. My pet theory on why you get 45519744 instead of the right answer is that your 32-bit computer lost the precision on the last digits.
