Rounding and accuracy

Use 2 decimal places for everyday tasks such as shopping, cooking, or estimating fuel costs, since small errors are harmless there. Use 4 decimal places for technical reports or pricing calculations. Keep 6 or more decimal places only for laboratory, engineering, or scientific work where exact precision matters.
