Supported bases
Choose binary (2), octal (8), decimal (10), or hexadecimal (16). Input digits are validated against the selected base before calculation.
Division behavior
Division uses whole-integer quotient and remainder, which avoids pretending that a repeating fractional value is an exact integer-base result.
Exact integer math
Calculations use BigInt rather than floating-point Number arithmetic, so long integer inputs are not rounded within the stated input limit.
Frequently asked questions
Are results saved or uploaded?
The calculation runs in your browser. Tooliyapa does not require an account to use this calculator.
Should I verify an important result?
Yes. For financial, health, academic, engineering, legal, or other consequential decisions, verify the inputs, assumptions, and result against an appropriate authoritative source or qualified professional.
