How to use these tools

Choose the most specific tool for the job, preserve the required precision and check whether rounding changes the practical result. The random number generator is suitable for ordinary selections and demonstrations, but it is not presented as a cryptographically secure source for passwords, security tokens or regulated draws.

  1. Choose the operation and enter values in the requested format.
  2. Check signs, brackets, units and decimal precision.
  3. Repeat the calculation when a result will be used in an important decision.
  4. Use a specialist or independently verified method for security-critical work.
