Important limitations
This page treats a negative whole-number input as applying the negative sign to the entire mixed number.
The sign applies to the whole mixed value
Enter whole part −2, numerator 1 and denominator 3 to represent −(2 + 1/3) = −7/3. It does not mean −2 + 1/3. The fraction part uses a nonnegative numerator and positive denominator; if the numerator exceeds the denominator, the normalized mixed output carries extra wholes. Components and their combined numerator must remain in the exact integer range supported by the form.
