Modular Exponentiation Calculator

This tool performs modular exponentiation calculations to help you find the remainder of a number raised to a power divided by a modulus.

This calculator enables you to compute the result of a base a raised to an exponent b in the context of modulo n, represented as a^b % n.

How to Use:

Enter the value for the base a in the “Base” field.
Enter the value for the exponent b in the “Exponent” field.
Enter the value for the modulus n in the “Modulus” field.
Click the “Calculate” button to display the result in the “Result” field.

How it Calculates:

The calculator uses an efficient method known as exponentiation by squaring to compute large powers modulo a number. This method greatly reduces the number of operations needed, allowing for the quick computation of large values.

Limitations:

This calculator strictly performs integer arithmetic and does not handle negative numbers or non-integer values. The input fields require valid numerical input for an accurate computation. The modulus n must be greater than one for meaningful results. The current implementation is also limited by the precision of JavaScript’s number handling capabilities.
