Frequently Asked Questions
How precise are the mathematical calculations?
Our calculators use JavaScript's floating-point arithmetic, which provides about 15-17 significant digits of precision. This is sufficient for most practical calculations.
Can these replace a scientific calculator?
For common calculations, yes. Our scientific calculator includes most functions found on standard scientific calculators. For specialized mathematical work, dedicated software may be more appropriate.
