Precision and calculation record

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

This rough total-water range includes water in food. Heat, exercise, diet and health change needs. Keep fresh water freely available; do not ration water to this estimate. Illness, dehydration or a marked change in drinking needs veterinary assessment. This is not an IV-fluid calculation.

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