Tried Python:

    >>> type(1e9)
    <class 'float'>
    >>> round(1e9)
    1000000000
    >>> round(1e12)
    1000000000000

However:

    >>> round(1e24)
    999999999999999983222784

So I tried:

    >>> import decimal
    >>> decimal.Decimal("1e24")
    Decimal('1E+24')
    >>> int(decimal.Decimal("1e24"))
    1000000000000000000000000

which is more like it.
