Pro Tips

Use significant figures for scientific measurements to preserve precision.

Banker's rounding is commonly used in financial calculations to reduce rounding bias.

Round to nearest 5 or 10 for estimates, and to nearest 0.05 for pricing.

Always specify the rounding mode when documenting calculations.
