Frequently Asked Questions

What's the difference between degrees and radians?

Degrees divide a circle into 360 parts, while radians use the radius length as the unit. One full circle = 360° = 2π radians. Toggle the mode with the DEG/RAD button.

How do I use the memory functions?

MS stores the current display value in memory, MR recalls it, MC clears memory to zero, and M+ adds the current value to what's already stored in memory.

What's the difference between log and ln?

log() calculates the base-10 logarithm (common logarithm), while ln() calculates the natural logarithm (base e). ln is commonly used in calculus and natural sciences.

Can I calculate complex expressions?

This calculator processes operations sequentially. For complex expressions with multiple operations, consider breaking them into steps or using parentheses carefully.

What happens if I get an error?

Errors occur with invalid operations like division by zero, square root of negative numbers, or factorial of non-integers. Press C or AC to clear and start over.

How accurate are the calculations?

The calculator uses JavaScript's built-in math functions with double-precision floating-point arithmetic, providing about 15-16 decimal digits of precision for most operations.
