Assumptions
The calculator uses real-number arithmetic unless complex square or quadratic roots are explicitly shown. Decimal displays can be rounded while calculations retain normal browser numeric precision.
Limitations
- Factorials are limited to integers from 0 to 170.
- History and memory last only for the current page session.
Frequently asked questions
Does the Scientific Calculator accept decimals and negative values?
It accepts them wherever the selected operation permits. Invalid domains are identified before a result is shown.
How are decimal results rounded?
Calculations retain JavaScript numeric precision and display a readable number of significant digits. A displayed decimal may therefore be rounded.
Are entries stored?
No. The calculation runs in your browser and this page does not store the values you enter.
