By default, the random numbers will +be uniformly distributed over the range 0 to 1. The number of lines +of output, number of columns (random numbers) per line, and number of +significant digits in each number may all be set by the caller. +.ih +EXAMPLES +Generate a sequence of 100 random numbers and graph them on the graphics +terminal in point plot mode.
