How it works
Each number is drawn uniformly from the range you set, so every value between the minimum and maximum has an equal chance. When you ask for unique integers, the generator shuffles the available numbers and takes the first few, which guarantees no repeats.
How to use the Random Number Generator
Enter the values requested by the tool and start with one realistic example. Read the result together with its unit or label, then change one input at a time if you want to compare options. Keeping a note of the original figures makes the calculation easier to check later.
A result is only as useful as the values and settings entered. Try a simple known example if you want to check your working.
