CalculatorPro vs 计算器(多进制)

Your system calculator says 0.1 + 0.2 = 0.30000000000000004. CalculatorPro doesn't. Arithmetic runs on exact rational numbers, not floating point. 1 ÷ 3 × 3 is 1. 19.99 × 3 is 59.97. Results that must be approximate — trig, logarithms — are marked with ≈, so you always know which numbers you can copy into a contract. — Accurate • Arithmetic, integer powers and decimals: zero error • 1 ÷ 3 shows its repeating digits with an overline, not a string of 333333 • sin(30°) = 0.5 and sin(180°) = 0, not 1.22e-16 • log(100) = 2 (many calculators give you the natural log, 4.605) • 200 + 10% = 220, not 200.1 — Calculates as you type • Live results — no need to press equals • Parentheses, backspace and percent at hand; edit the expression any time • Errors underline the exact fragment at fault and explain in plain language — Nothing gets lost • Every calculation is kept, with full-text search that stays instant across thousands of entries • Notes, pinning, and export to CSV / JSON / Markdown • History stores exact values — reload one in three years and no precision is lost — Two keypads, swipe to switch • Basic: a superset of the system calculator — parentheses, backspace, correct percentages • Scientific: trig, hyperbolics, logs, roots, factorials, modulo, DEG·RAD·GRAD — Also • 20 themes; light and dark are chosen independently, including Blueprint, Terminal, Receipt and Neon • Distinct haptics for digits, operators and equals • Full hardware keyboard mapping; split layout in landscape on iPad • Complete VoiceOver support and Dynamic Type — Privacy No data collected. No account, no network, no analytics. History never leaves your device. No in-app purchases, no subscription, no ads.

这是一款同时支持十进制，二进制，十六进制的计算器App，它可以将两个十进制/二进制数/十六进制数 相加、相减、相乘或相除。 用户可以通过输入两个十进制数来进行计算，这个App支持小数点的计算，并且可以进行四舍五入，用户也可以选择将结果转换成二进制数/十六进制数。 除此之外，这个App还提供了一个十进制数/二进制数/十六进制数转换功能。用户可以将十进制数转换成二进制数，或者将二进制数转换成十进制数。 这个App界面简洁明了，易于使用。用户可以快速计算出十进制数/二进制数/十六进制数的运算结果，并且可以随时转换进制。 总之，这是一个功能全面、易于使用的十进制/二进制/十六进制计算器App，适合需要进行十进制/二进制/十六进制数学运算的用户使用
