Frequently Asked Questions About Scientific Calculator
Got questions about using trig functions or constants? Read the answers below.
Q.How do I change between Radians and Degrees?
Toggle the "RAD/DEG" key on the layout. The indicator on the screen will update dynamically to show DEG (Degrees) or RAD (Radians).
Q.What is the difference between log and ln?
The "log" key calculates the common base-10 logarithm. The "ln" key calculates the natural logarithm based on the constant e.
Q.Does it support keyboard inputs?
Yes, standard numeric values, arithmetic signs (+, -, *, /), and parentheses can be entered using physical keyboards.
Q.How is data security handled?
CanvaTools evaluates everything inside client-side JS without submitting calculations to any external servers, ensuring 100% local safety.
