Random Number with x Digits
Generates one or more random numbers with a specified number of digits. If "without leading zero" is selected, the random number generated is a natural number with exactly this number of digits. The first digit is not a zero, but a digit from 1 to 9. The other digits can also be 0. If "allow leading zero" is selected, the number can also begin with a zero. If "omit leading zeros," is selected, numbers with fewer digits are also output, those who would otherwise have started with zero.
Please specify the number of digits the random number should have. If no number of digits is specified, or the "Random number of digits" button is pressed, a random value between 1 and 9 will be selected for the length of the number. The amount of random numbers specifies how many numbers will be generated. They will all have the same length.
If you try to create random numbers yourself, you're very likely to make systematic errors that favor some digits in terms of frequency of occurrence and disadvantage others. For example, zero is often not sufficiently considered within a number. However, if you remember to include zero, you'll tend to use it too often. A random number generator for numbers with a specific number of digits or length doesn't make such errors; all digits are represented equally often on average.
An example of this application: In third grade or so, children often learn how to subtract three-digit numbers from each other. To create a practice exercise, generate two random three-digit numbers. The task is now to subtract the smaller of these two numbers from the larger number.
