Paste a column or list of numbers — one per line, or separated by commas or spaces — and get the total sum together with the average (mean), minimum, maximum, count and median. Any token that is not a valid number, such as a header word or a currency label, is simply ignored so you can paste messy data.
Numbers may include decimals, negative signs and scientific notation; the median is computed from the sorted values and averaged when the count is even. All calculation happens locally in your browser and nothing you paste is uploaded anywhere.
