Scientific Calculator
Evaluate scientific expressions with trigonometry, logarithms, powers, roots, factorials, constants, memory, history, and DEG/RAD angle modes.
Supports trigonometry, logarithms, roots, powers, absolute values, exponentials, constants, and factorials.
mod is the remainder operator, not percent

Scientific functions for numeric expressions
The English scientific calculator intent is broad but practical: evaluate a typed expression, use trig and log functions, switch between degrees and radians, and keep common memory controls visible.
- Trigonometry: sin, cos, tan and inverse functions through the 2nd key.
- Logarithms and exponentials: log, log2, ln, exp, powers, and roots.
- Expression support: parentheses, operator precedence, factorial, absolute value, pi, e, and modulo as a remainder operator.
theta_deg is an angle in degrees and theta_rad is the same angle in radians.
Scope and limits
The expression parser runs in the browser without eval. Results are rounded for readable display, so use a specialist high-precision tool when exact arbitrary-precision arithmetic is required.
