Enter a scientific expression

Type an expression or use the keypad. Parentheses, powers, roots, logarithms, factorials, constants, and standard scientific notation such as 1.2e6 are supported. Press Enter or = to evaluate.

DEG and RAD angle modes

DEG treats trigonometric angles as degrees, so sin(30) is 0.5. RAD treats them as radians, so sin(pi/6) is 0.5. Inverse trig results follow the selected angle mode.

Powers, roots, and precedence

Exponentiation is right-associative: 2^3^2 means 2 raised to the ninth power and equals 512. Exponentiation also binds before unary minus, so -2^2 is -4 while (-2)^2 is 4.

Logarithms and exponentials

log(x) is base 10, ln(x) is the natural logarithm, and exp(x) calculates e to a power. Log inputs must be positive real numbers.

Factorials and real-number limits

Factorial accepts whole numbers from 0 through 170. This calculator evaluates supported real-number expressions only; it does not provide complex-number, graphing, symbolic algebra, matrix, statistics, or calculus modes.

Ans, memory, and history

Ans uses the previous successful raw result. MC, MR, M+, and M− manage page-session memory, while History keeps up to 25 successful calculations. Errors do not replace a prior successful Ans or memory value.

Floating-point results

Calculations use standard browser double-precision floating-point arithmetic. Most results provide about 15–17 significant decimal digits internally, while the display is limited to a concise 12-significant-digit presentation. Some decimal and transcendental results are necessarily approximate.
