10-Radix Big-Integer.cpp

Library for 10-radix signed BigInteger, including all kinds of arithmetic operation. Including:

• add ( $A+B$ )
• subtract ( $A-B$ )
• multiply ( $A*B$ )
• divide (abs round down) ( $\lfloor A/B \rfloor$ )
• modulo ( $A\mod B$ )
• power ( $A^B$ )
• log (abs round down) ($\lfloor \log_A B\rfloor$ )
• root (abs round down) ($ \lfloor \sqrt[A]{B} \rfloor $)
• greatest common divisor ($ \gcd (A, B) $)
• factorial ($ A! $)
• combination ( $C(n, m)$ )

Arbitrary-Radix Big-Integer.cpp

Library for arbitrary-radix unsigned BigInteger, including Base-Conversion between radix 2 to 62, with time complexity $O(n \log ^2 n)$.
