小数↔分数。アップグレードは循環小数＆インチ変換ディスプレイを含みます

The Decimal to Fraction calculator converts a decimal to fraction or fraction to decimal.

The 'Upgrade' In-App purchase version supports repeating decimals both to and from decimal and fraction conversion. And displays your input values to an imperial inch style number line (not actual size) that is accurate to ~0.001". Very handy for easily and accurately converting decimals and odd fractions to a measuring tape.
