MATH
Arithmetic & number operations calculators
Add, subtract, multiply or divide two supplied values, take an absolute difference, or round a real number at a fixed integer scale. This is useful when the original value is zero.
Choose the right tool
Use percentage change in the neighboring group when a relative comparison is appropriate. An absolute change retains the supplied quantity’s units. Division requires a strictly positive denominator. Nearest rounding resolves halfway ties toward positive infinity, including negative inputs; these are binary real-number calculations without a financial-decimal guarantee. Decimal-place rounding uses a visible precision selector and half-up ties toward positive infinity; tenth, hundredth and thousandth links open explicit presets on one calculator. Floor quotient needs a positive divisor. Two-bit AND, OR, XOR and NOR return one Boolean result from supplied bits. Decimal comparison is numerical ordering, not exact fraction simplification.
