Evaluate real-number expressions with scientific functions, factorials and explicit degree / radian modes.
Display precision does not round inputs or exact calculations. Exact result strings and generated reports retain their stated precision.
Enter values or load the example to begin.
Real-number expressions with + − * / ^, parentheses, factorial ! and postfix percentage %. Use explicit multiplication. Functions: sin/cos/tan, asin/acos/atan, sqrt/cbrt/abs, ln/log/exp, floor/ceil/round, min/max, pow and mod. Constants: pi and e. Scientific factorial: 0–170; use Probability for exact larger factorials.
Calculation worker deadline: 10 seconds. Results are invalidated on input or setting changes. Reports are limited to 4 MiB. No values are persisted or sent to a server.

Ten equal-width bins; left edge inclusive, final upper edge inclusive. A constant dataset uses one bin. Full unrounded frequencies are below and in the JSON report.
Your numbers, expressions, matrices and optional data files stay on your device. Calculations run in a bounded local worker using self-hosted code, without uploads, accounts or application input history.

Integer, fraction, combinatorial and supported rational algebra operations use exact BigInt rational arithmetic, within explicit resource limits. Scientific functions, descriptive statistics and labeled irrational-root approximations use finite IEEE-754 numbers. Display precision never changes exact inputs, rational decisions or stored data.
Invalid input, incompatible dimensions, division by zero, unsupported domains or resource limits produce a clear message and clear prior outputs. Undefined sample variance with one observation is labeled explicitly. Reports are available only after a successful complete calculation.
No. Optional Statistics file selection reads UTF-8 locally and shows filename, size and loading/ready/error status. Failed imports preserve previous working text. Manual replacement, sample and clear remove obsolete file selections. Downloads and clipboard copies exist outside the application only when you request them.
