Frequently Asked Questions
Can I enter negative or improper fractions?
Yes. Put a minus sign on the numerator or denominator. The result is normalized to a positive denominator, and improper results also show a mixed number when there is a remainder.
Can I enter a mixed number directly?
Enter fractions as numerator and denominator pairs. Convert a mixed number first: 2 1/3 is 7/3, while -2 1/3 is -7/3. Decimal inputs are not accepted.
Is the result exact?
The simplified fraction uses exact integer arithmetic. Each input accepts up to 15 digits plus an optional sign. The decimal display is approximate and rounded to 12 significant digits.
Why is a denominator of zero rejected?
A fraction with a zero denominator is undefined. Division by a fraction whose numerator is zero is also rejected. A zero numerator is otherwise valid.
Does Kalika keep my fraction inputs?
