Free online random digit pair generator. Just press a button and get your random pair of digits going from 00 to 99. You can generate as many random digit pairs as you need, exclude certain digits, and output them in a custom format (for example as a list or a comma-separated string). Created by developers from team Browserling.
This tool generates random pairs of digits and you can individually configure which digits will appear in the first position of the pair and the second position of the pair. The first option (First Digit Filter) allows you to exclude certain digits from the first value, and the second option (Second Digit Filter) lets you do the same for the second value. For example, if you enter the value "2" in the first option, then all pairs beginning with "2" will be removed from the print-out (that is, the pairs 20, 21, 22, 23, 24, and so on to 29 will be filtered out). If you also set a value in the second option, then even more pairs will be removed that end with this digit. For example, if the first value is still "2" and the second value is set to "1", then 01, 11, 20-29, 31, 41, 51, 61, 71, 81, and 91 will be removed from the possible results. In the options, you can also set the pair separator symbol and specify the number of pairs in the output. Additionally, the "Allow Repetitions" option lets you output only the unique digit pairs (in total there are 100 so you can't print more than 100 results). This program is often used to generate specific number patterns, which can be used to simulate a 100-sided dice and mnemonics for passwords. It can also be useful to show in practice how probability theory and combinatorics work. Randomabulous!
This is an example from a game. The task was to quickly simulate 10 repeated double-dice throws on a game table. To do it, we remove the digits that don't appear on both dice (7,8,9,0). We separate the result by a dash symbol "-" and in the output get the simulation print-out.
In this example, we create a logic puzzle – a person must look at a series of random digit pairs and find a pattern. Here we use only two-digit numbers that are divisible by 5 without a remainder. The first filter option is unchanged (we allow the numbers to start with any digit), and from the second digit of the number we remove all digits except 5. Additionally, the repeated digit pairs are prohibited via the "Allow Repeated Pairs" option that is set to false.
This example creates a long random string of binary digit pairs. The long binary string can serve as an exercise for converting a binary number to another number system (for example, decimal). To generate it, we first remove digits 2-9 from both pair positions so that only digits 0 and 1 are allowed. It's important to remember that the number of digits in output will be twice as big as the count (in this case there are 40 digits in the output as 20 pairs are printed).
You can pass options to this tool using their codes as query arguments and it will automatically compute output. To get the code of an option, just hover over its icon. Here's how to type it in your browser's address bar. Click to try!
