Frequently Asked Questions

How accurate are the trigonometric functions?
Our scientific calculator uses JavaScript's built-in Math functions, which provide high accuracy for most calculations. For extremely precise scientific work, specialized software may be more appropriate, but this calculator is suitable for educational and general use.
What's the difference between DEG and RAD modes?
DEG (degrees) and RAD (radians) are two different units for measuring angles. In DEG mode, angles are measured in degrees (0-360°), while in RAD mode, angles are measured in radians (0-2π). The mode you choose affects how trigonometric functions (sin, cos, tan) interpret input values and calculate results.
How do the memory functions work?
Memory functions allow you to store and recall values during calculations: MS (Memory Store) saves the current displayed value to memory, MR (Memory Recall) displays the stored value, M+ adds the current value to memory, M- subtracts the current value from memory, and MC (Memory Clear) clears the stored value.
What's the maximum number size this calculator can handle?
This calculator can handle numbers within JavaScript's numerical limits (approximately ±1.7976931348623157e+308). For extremely large or small numbers, scientific notation is used automatically. If a calculation exceeds these limits, "Overflow" or "Infinity" will be displayed.
