Everything beyond that is silently rounded: on most systems <code>1e20 + 1<\/code> evaluates to exactly <code>1e20<\/code>, and a 60-digit product keeps at most 17 correct digits. The rounding is invisible on screen but real, and it compounds through every subsequent calculation \u2014 a serious problem when you need to verify a large product, count combinations, or check an algorithm digit by digit.<\/p>\n<p>This calculator avoids floating point entirely. Each input is rewritten as one BigInt integer \\(V\\) with a decimal scale \\(S\\), and every operation \u2014 addition, multiplication, exponentiation by squaring, Newton-iteration square roots, the Euclidean algorithm for GCD, term-by-term factorials \u2014 runs on those integers with no limit of 15\u201317 digits. The only place rounding can occur is division and square root at the requested decimal place, and the <strong>Exact or rounded?<\/strong> box tells you plainly which case you are in, so an \u201cExact\u201d verdict means every single digit shown is correct.<\/p>\n<p>The remaining output boxes help you handle long answers: <strong>Significant digits in the result<\/strong> gives the exact length, and <strong>Scientific notation<\/strong> shows the magnitude with 11 significant digits \u2014 handy for comparing sizes, and easy to convert further with the <a href=\"https:\/\/wpcalc.com\/en\/mathematics\/scientific-notation-calculator\/\">scientific notation converter<\/a>. Typical uses include checking big multiplications by hand, combinatorics, verifying homework on huge numbers, and any task where a double-precision tool would quietly round your answer.<\/p>\n<h2>Limits, Conventions and Practical Tips<\/h2>\n<ul>\n<li><strong>Input size:<\/strong> each number may have up to 1,000 digits before the exponent, with an exponent up to \u00b110,000. Results longer than 1,000,000 digits are refused with a warning rather than freezing the page.<\/li>\n<li><strong>Powers and factorials:<\/strong> for x ^ y the exponent must be a whole number from 0 to 10,000 (negative powers give non-terminating fractions and are rejected); n! accepts whole numbers from 0 to 5,000. For smaller n, the dedicated <a href=\"https:\/\/wpcalc.com\/en\/mathematics\/factorial-calculator\/\">factorial calculator<\/a> shows the step-by-step product.<\/li>\n<li><strong>Division and roots:<\/strong> a \u00f7 b is rounded half-up to the requested decimal places, and the calculator reports whether the division came out exact. \u221ax first checks whether x is the square of a terminating decimal; if not, the root is rounded half-up and flagged.<\/li>\n<li><strong>Remainder sign:<\/strong> a mod b takes the sign of the first number, like the % operator in JavaScript and C. If you need the always-non-negative (Euclidean) remainder, adjust the result by adding |b| when it is negative.<\/li>\n<li><strong>GCD and LCM on decimals:<\/strong> both operands are scaled to a common power of ten first, so GCD(2.5, 1.5) = 0.5 works naturally. For everyday whole numbers you can also use the <a href=\"https:\/\/wpcalc.com\/en\/mathematics\/gcf-calculator-greatest-common-factor\/\">GCF calculator<\/a>.<\/li>\n<li><strong>Modular arithmetic:<\/strong> if you only need x ^ y mod m, the <a href=\"https:\/\/wpcalc.com\/en\/mathematics\/modular-exponentiation-calculator\/\">modular exponentiation calculator<\/a> avoids building the huge power in the first place.<\/li>\n<li><strong>Formatting:<\/strong> use either a dot or a comma as the decimal separator, but never both in the same number; minus signs and spaces are cleaned up automatically. Results use an ASCII minus so they paste cleanly into other tools, and every answer has a <em>Copy result<\/em> button.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Performs exact arithmetic on very large numbers: add, subtract, multiply, divide, powers, factorials, square roots, GCD and LCM with up to 1,000 digits per number and no floating-point rounding.
