How to input scientific notation?

Use E or e to represent powers of 10, for example 1.23E+5 represents 1.23×10^5=123000. You can also input 1.23*10^5.

How to switch angle units for trigonometric functions?

Calculator defaults to radians. For degree calculations, convert first: degrees × π/180 = radians, or use degree conversion function.

How to use memory functions?

MS: Store current display value to memory; MR: Recall memory value; MC: Clear memory; M+: Add current value to memory.

How to handle division by zero errors?

Division by zero shows error message. Some functions may also produce errors at specific points, like log(0) or sqrt(-1).

What keyboard shortcuts are available?

Number keys 0-9, operators +-*/, Enter confirm, Escape clear, parentheses (), decimal point ., etc. Supports common keyboard operations.

How high is calculation precision?

Uses IEEE 754 double-precision floating-point, approximately 15-17 significant digits. Sufficient precision for most calculation needs.

How to calculate complex expressions?

Supports complete mathematical expressions following operation precedence. Recommend using parentheses to clarify operation order, complex calculations can be done step by step.

How long is history record saved?

History records are saved locally in browser, clearing browser data will delete records. Recommend saving important calculation results promptly.
