Computes 128-bit result of multiplication of two 64-bit unsigned integers.

Advances the begin iterator to `it`.

Reports an error if using the automatic argument indexing; otherwise switches to the manual indexing.

std::istream/std::streambuf use std::char_traits<char>::to_int_type, to ensure that std::char_traits<char>::eof() and the character 0xFF do not end up

return whether the iterator can be dereferenced

If this bigint has a bigger exponent than other, adds trailing zero to make exponents equal. This simplifies some operations such as subtraction.
