Built for Precision & Speed

A zero-dependency scientific calculation engine designed for students, researchers, and engineers.

Floating-Point Mitigation

Uses accurate decimal serialization to prevent standard JavaScript rounding bugs like 0.1 + 0.2 = 0.30000000000000004.

Trigonometric & Hyperbolic

Supports sin, cos, tan, asin, acos, atan, sinh, cosh, tanh in both Radian and Degree angular modes.

Calculation History Ledger

Every evaluated expression is logged to an accessible history drawer with 1-click restore into the active expression.

Full Numpad Key Bindings

Type seamlessly with standard keyboard number keys, enter, backspace, and operational shorthand hotkeys.

Memory Registers (M+, M-, MR)

Store intermediate scalar constants and recall cumulative calculation sums across multi-step problems.

Responsive Touch Glass Keypad

Optimized key sizing and haptic feedback animations engineered for tablets, phones, and desktop screens.
