This article is aimed at technical people. In short, for non-technical people, Blooft takes reasonable measures such as limiting decimal precision to 11 or 12 points to avoid most precision issues inside calculation results. Computers are inherently imperfect, so calculations can still be inaccurate. Use the calculator at your own risk and not for mission-critical calculations (such as financial, medical, construction, and accounting).

When you use Blooft’s calculator for precision-critical tasks, be aware that it can produce errors. We are working to improve accuracy, but computers are inherently imperfect.

The calculator rounds results in a limited number of decimal places (11 or 12), which may cause some values to appear truncated. For example, while most precision issues come after the 11th or 12th decimal place, this is not always a perfect solution. JavaScript, the language behind this tool, still struggles with representing large numbers and certain decimal values accurately. Limiting the decimal places fixes most of the floating point arithmetic issues, and many calculators do similar methods.

Do not use this tool for mission-critical calculations. We are not responsible for any damages or consequences resulting from inaccurate calculations. The calculator is provided ‘as-is’ and without any warranties or guarantees.

These errors arise from floating-point arithmetic, which can result in minor precision errors—such as the infamous 0.1 + 0.2 = 0.3000000000004. While Blooft doesn’t exhibit this specific error, many other non-obvious precision issues can arise.

Additionally, programming languages like JavaScript can struggle with handling large numbers. For example, if you evaluate 99999999999999999999, JavaScript will return 100000000000000000000.
