Models approximate math and get large or precise sums wrong; this computes the exact result.

3 tools

Exact calculation: evaluate math expressions (arithmetic, powers, roots, trig, logs, factorials), convert numbers between bases (binary, hex, decimal, and more), and convert Roman numerals. Computed locally with exact results, where a model would otherwise approximate.
