Scientific Calculator accuracy and testing

Formula source

• The calculator uses standard mathematical algorithms: * **Trigonometry:** Calculates the ratio of sides for a given angle using the unit circle properties. Note: Input angles must be in Radians. * **Logarithms:** Finds the power to which a base (10 or e) must be raised to equal the input number. * **Exponents:** Multiplies a base number by itself a specific number of times.

Test cases

Known limitations

• This page documents the checked-in calculator logic and does not certify results for every real-world edge case.
• Use the result as a planning estimate unless the calculator page states a stricter purpose.

Assumptions

• Trigonometric inputs are interpreted as radians.
• Binary operations use both Value 1 and Value 2; unary operations ignore Value 2.
• Logarithms and square roots follow real-number rules, so invalid inputs may return NaN.

Unit handling

• Operation accepts one of the configured options.
• Value 1 (x) accepts numeric values.
• Value 2 (y) accepts numeric values.

Rounding rules

• Number displays use up to 2 decimal places in the calculator UI.
