Normalized BigInt arithmetic preserves exact fractions, signed mixed numbers and cross-cancellation. Rounded decimal and percentage views stay separate from the exact answer.
Fraction Calculator inputs and calculations remain in browser memory. No external processing service receives entered values. Existing website infrastructure may log ordinary page requests; copying occurs only when selected.
Use signed integers, finite decimals, a/b fractions or mixed numbers such as -1 1/2. The mixed-number sign applies to the whole value, so -1 1/2 is -3/2. Finite decimal strings are parsed exactly, not as binary floating-point fractions.
The calculator finds an exact common denominator using the greatest common factor of the denominators, scales both numerators, applies the operation and reduces the result. Multiple operands are evaluated from left to right.
BigInt numerator/denominator arithmetic cross-cancels common factors before multiplication. Division multiplies by the reciprocal of a nonzero fraction. Denominators are normalized positive and every result is reduced by the GCF.
The reduced fraction and mixed number are exact. Decimal and percentage strings are separately rounded at the selected precision and marked approximate when necessary; rounding never changes the stored rational result.
A faithful shaded-bar illustration is shown only for nonnegative results up to three wholes with a denominator no larger than 24. Negative or huge values retain their exact numerical explanation without a misleading picture.
Use two to ten operands. Individual integer parts are bounded to 60 digits and operands to 190 characters; decimal parsing also limits decimal places. Zero denominators and division by zero-valued fractions are rejected. No scientific notation is interpreted in this tool.
