Decimal → Fraction Converter
Convert decimals to fractions in lowest terms, show mixed-number output, and verify with a decimal check.
Exact mode uses the digits you typed. Example: 2.375 → 2375/1000 → 19/8. This is exact for the written decimal, even if the value originally came from rounding.
Approximation mode finds a clean fraction close to the decimal using a denominator limit. This is helpful for measurement decimals like 0.3333 → 1/3.
Pattern mode converts repeating decimals by formula. Example: 0.(3) = 1/3 and 0.1(6) = 1/6. Enter only digits (no dots).
Batch mode converts each line and returns a simplified fraction. Use Approx mode for “nice” fractions from rounded decimals.
