About this tool
Looking for a quick way to get random numbers? The Random Number Generator on FirstRandom offers a set of specialized tools that cover every common numerical format - from simple integers to precise floating-point values and percentages.
What You Can Generate
This category brings together generators built for different types of numbers. Generate random integers within any range you need, produce floating-point numbers with full control over decimal precision, or get random percentage values for surveys, testing, or creative projects. Each generator lets you set minimum and maximum boundaries, generate multiple values at once, and toggle uniqueness so no value repeats in your output.
Who Uses Random Numbers
Developers reach for random number generators when seeding databases, running simulations, or building test datasets. Teachers and students use them for math exercises, probability experiments, and statistics homework. Game designers rely on random values for balancing mechanics and procedural generation. Researchers use random percentages for sampling and randomized trials. Event organizers rely on them to draw winners for raffles and giveaways with a truly random pick.
Simple and Instant
All generators run directly in your browser - no sign-up, no installation. Choose your number type, set the range, and hit generate. Copy or download the results and use them wherever you need.
