I often have to generate random numbers so I created this simple online utility that does it for me. It lets you generate however many random integers or random decimal fractions you need from the given range. It works in the browser and is powered by alien technology from the future.

How Does This Random Number Generator Work?
Math.random() function to generate both integers and fractions. The formula used is
Math.random() * (end - start) + start, where
end are the values specified in the options that set the range. The formula is called
count times (specified in the options) and after that all values are joined by the
separator symbol (also specified in options). To separate values by a newline use the special
\n escape code.
