Calculation Steps
b^e mod m
Modular exponentiation finds the remainder after raising a base to a power and dividing by a modulus. It is a core operation in cryptography and number theory.
Example: 2^10 mod 1000 = 24.
Can the exponent be negative?
No. This calculator supports non-negative integer exponents only.
Does this handle large numbers?
Yes. It uses BigInt arithmetic for integer inputs.
Why is modular exponentiation useful?
It keeps numbers manageable while preserving the remainder behavior needed in cryptography.
Can the modulus be zero?
No. Modulus zero is undefined.
