Frequently Asked Questions
What occurs during division by zero?↓
Division by zero is undefined. The calculator returns 0 and guards against software crashes.
What does modulo (mod) calculate?↓
The modulo operator yields the integer remainder after division (e.g. 10 % 3 = 1).
Can negative exponents be computed?↓
Yes. A negative exponent computes the reciprocal power (e.g. 2 ^ -2 = 1 / (2^2) = 0.25).
What is a limitation of standard floating arithmetic?↓
Certain binary representations (like 0.1 + 0.2) have tiny precision rounding artifacts, which this tool formats to four decimal places.
