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

A starting estimate for healthy adult dogs. Puppies, pregnancy, lactation, illness and weight-change plans need a veterinarian. Individual needs vary; monitor body condition with your vet. Food grams assume this food supplies the entire calculated energy amount, including treats.

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