# Arbitrary Sized Integers

Unlike cpython, pkpy's int is of limited precision (64-bit).

For arbitrary sized integers, we provide a builtin long type, just like python2's long. long is implemented via pure python in _long.py.

This feature is still under development. Some operations are missing, and some operations are not optimized.

# Create a long object

You can use L suffix to create a long literal from a decimal literal. Also, you can use long() function to create a long object from a int object or a str object.

a = 1000L
b = long(1000)
c = long('1000')
assert a == b == c

a = 2L         # use `L` suffix to create a `long` object
print(a ** 1000)
