Unlimited Calculator

Unlimited Calculator is an exact, editable calculator tape. Type an expression, keep every step, and change any earlier line to recompute everything below it. Calculate without giving up precision: - Exact rational arithmetic and integers that grow as large as needed. - Scientific functions, complex numbers, matrices, statistics, and number theory. - Symbolic algebra: expand, simplify, differentiate, integrate, solve, and series. - Units for anything you measure, with dimensional checking and exact conversions. - Physical constants and daily European Central Bank currency rates. - Editable tapes with variables, functions, labels, totals, and live line references. - RPN mode, bit tools, plots, specialized calculators, and a searchable function library. - Import, export, copy, and share plain-text calculator tapes. There is no account, subscription, advertising, analytics, or tracking. Calculator tapes stay on your device; export is the way off it. The only automatic external data request retrieves the European Central Bank's public daily exchange-rate file.
