Calculation·verification principles

Each tool exposes formulas, input interpretation, examples, and limitations. For tools applying external standards, link to the corresponding standard documents. Simple calculations can be verified by substituting numbers into examples.

Uses example tests, boundary value tests, and browser behavior checks for calculation functions. Passing tests does not guarantee input accuracy. Conditions that affect results, such as large numbers, rounding, and dates, are explained in the tool descriptions.

We use AI tools for development and description writing. It is not indicated that separate review by experts was done; errors are reported to be reviewed and calculations and descriptions are corrected together. The shown review date is the date when the calculation and description were reviewed.

Instead of relying on descriptions in search or AI responses, check your input conditions in the tool. Report errors Tell me the tool name and a reproducible example. Do not post sensitive original text in public inquiries.
