Calc goes beyond giving you a number. Each calculator shows the formula with your inputs, assumptions, limits, and sources. It distinguishes exact calculations from estimates and external-data results, and many tools also support reverse calculations or scenario comparisons. Results can be copied, shared, emailed, or saved as a PDF. Localization is built into the product, not added as an afterthought.
