Convert a terminating decimal to an exact simplified fraction locally, without rounding.
Enter ASCII digits 0–9 with an optional leading + or -. A dot or comma is a decimal separator: 0.125 and 0,125 both give 1/8. A comma never groups thousands; for example, 1,000 is interpreted as 1. .5 and ,5 are accepted, as are integers. The integer part and fractional part each allow at most 12 digits. Raw input must not exceed 64 characters before leading/trailing whitespace is trimmed. Scientific/exponential notation, thousands separators, a trailing dot/comma, fraction notation and repeating decimals are unsupported. BigInt arithmetic converts the terminating decimal exactly and reduces it by the greatest common divisor, without approximation or rounding. 0.333 is exactly 333/1000, not the infinitely repeating 0.333… or 1/3. The denominator is positive; -1.25 gives -5/4. Integer results omit the fraction bar, and zero is shown as 0. Conversion preserves the entered text; copy the result as needed. Clear restores the default input 0.125 and removes the result and copyable output. The Fraction calculator requires integer numerators/denominators; this tool directly converts decimal input to a fraction. Processing is local in your browser; input and results are not sent to a server.
