# Random Number Generator

Here we discuss list of online math calculators that help us for doing calculation easily.

### Generate Random Number

Generate one or more random numbers within a range that you define.Enter the minimum and maximum for the range you want and enter the number of numbers you want generated.You can also sort the generated numbers from lowest to highest, from highest to lowest, or choose to do not sort. Note that even if you choose not to sort that it is still possible for your numbers to be in some kind of order if they happen to be randomly chosen in order.

** Generate a Random Number for a PIN.**

To generate a 4 digit PIN without duplicate digits, choose Min = 0, Max = 9 and Generate 4 Numbers.

Example: 4 digit PIN without duplicates

A random number is a number chosen from a pool of limited or unlimited numbers that has no discernible pattern for prediction. The pool of numbers is almost always independent from each other. However, the pool of numbers may follow a specific distribution. For example, the height of the students in a school tends to follow a normal distribution around the median height. If the height of a student is picked at random, the picked number has higher chance to be closer to the median height than being classified as very tall or very short. The random number generators above assume that the numbers generated are independent of each other, and will be evenly spread across the whole range of possible values.

This calculator can create one or many random integers or decimals. It can deal with very large numbers with up to 999 digits of precision.A random number generator, like the ones above, is a device that can generate one or many random numbers within a defined scope. Random number generators can be hardware based or pseudo-random number generators. Hardware based random-number generators can involve the use of a dice, a coin for flipping, or many other devices.

A pseudo-random number generator is an algorithm for generating a sequence of numbers whose properties approximate the properties of sequences of random numbers. Computer based random number generators are almost always pseudo-random number generators. Yet, the numbers generated by pseudo-random number generators are not truly random. Likewise, our generators above are also pseudo-random number generators. The random numbers generated are sufficient for most applications yet they should not be used for cryptographic purposes. True random numbers are based on physical phenomenon such as atmospheric noise, thermal noise, and other quantum phenomena. Methods that generate true random numbers also involve compensating for potential biases caused by the measurement process.
