Home/Random Decimal
A number with a fractional part, drawn evenly between your two ends. For test data, for a measurement to work with, for anywhere a whole number would be too coarse.
Press Draw
Every value between the two ends is as likely as every other, to the number of places you asked for. Rounding is what decides the places, so the two outermost values come up about half as often as the rest.
Put the larger number in either box; if they are the wrong way round they are swapped rather than refused.
