Frequently Asked Questions
Why does sin(180°) sometimes show a microscopic decimal in computers?↓
Floating-point representations of π are finite approximations. This engine rounds values below 1e-15 to an exact zero.
Can negative numbers be passed to square root or logarithm?↓
Real numbers do not support negative square roots or non-positive logs. The tool guards these edge cases by returning 0 with an explanatory expression.
What is the maximum integer for factorials?↓
Standard JavaScript integers support exact factorials up to 18!, and double-precision floats overflow to Infinity at 171!.
What is a limitation of degree mode in calculus?↓
Calculus derivatives and Taylor series expansions for trigonometric functions are only valid when angles are measured in radians.
