Decimal places in numeric results and text downloads

Rounding changes displayed numbers, not the calculation. Text, fractions, matrices and CSV schedules keep their own formatting. Automatic keeps up to 12 significant digits, with money shown to cents where applicable.

Saved scenario

Save the current answer, then change an input to compare. This clears when you leave.

Formula and assumptions

For air temperatures at or below 50 F and wind speeds above 3 mph. This index describes exposed-skin cooling in shade, not an object temperature or a frostbite timer. This implementation accepts -100 to 50 F and winds up to 110 mph.

Automatic precision shows numbers to 12 significant digits. Thousands separators such as 1,000 are accepted; use a dot for decimals.
