About Scientific Calculator
Use an operation selector for one calculation at a time. This calculator handles arithmetic and selected scientific functions rather than parsing a typed expression. Trigonometric input is in radians, and Natural logarithm means log base e.
Unary and binary functions
Shows the second input only when the chosen operation needs it.
Real-number checks
Rejects non-finite outputs, such as division by zero or a square root outside the real domain.
Compact numeric output
Displays the result using up to twelve significant digits.
