Use the page’s decimal notation; separate values with spaces, semicolons or newlines. Signed decimals and scientific notation are accepted. Text, fractions, non-finite numbers and nonzero inputs rounded to zero are rejected. There is no preview of recognized values.

Limits: 100000 characters and 10000 values. A finite input list containing zero returns signed zero, determined by the number of negative factors, including -0. Otherwise, multiplication starts at 1 in input order. Intermediate overflow or underflow to zero rejects the calculation, even if later factors could bring the exact product back into range. JavaScript Number arithmetic can round; the display rounds to at most 15 significant digits without grouping. No arbitrary precision, steps or download.
