What you can do in Fraction Calc:
Whole Numbers:
It will only receive whole numbers as an input. Add, multiply, subtract, and divide. Division will provide a remainder where appropriate, rather than a decimal fraction.

Fractions:
It will receive whole numbers, numerators, and denominators as input. The resulting fraction from the mathematic operation will automatically be reduced to the lowest possible denominator. A pie chart will display the fraction portion of the resulting answer.

Conversions:
Convert from a decimal to a fraction by entering the decimal number in the field on the right side of the equality sign.

Operate the slider to determine the size of the denominator (from 2-8, 16, 32, 64, & 128) or type in the desired denominator in the field directly above the slider. The resulting fraction will be the closest approximation of the decimal based on the size of the chosen denominator.

If auto reduce switch is on, the fraction will be reduced upon conversion from decimal. If it is off, the fraction will retain the chosen denominator.

A glass will display the fraction as an appropriate liquid level, and will also display the decimal value as a red ring inside the glass at the appropriate level (if not exactly equal to the fractions decimal value).

Finally, if you enter a fraction it will convert to the decimal value when you press the done button.
