Formula Methodology & Standards
Every calculator published on Calcia undergoes algorithmic verification against recognized scientific, regulatory, and financial frameworks before release.
1. Regulatory Financial Compliance
Loan amortization, compounding intervals, and annual percentage yields (APY) strictly adhere to US Federal Reserve Regulation Z disclosure standards and standard commercial 30/360 day-count conventions.
2. Clinical Biophysical Standards
Health formulas utilize validated clinical models: Body Mass Index (BMI) conforms to the World Health Organization Quetelet classification, and caloric energy expenditure uses the Mifflin-St Jeor equation.
3. IEEE 754 Floating-Point Precision
All client-side arithmetic runs in TypeScript using double-precision IEEE 754 standards, with guard digits implemented to eliminate binary floating-point rounding errors common in web calculators.
4. Transparent Algebraic Citations
We reject opaque black-box scripts. Every calculator publishes its exact formula, variable definitions, and a worked numerical example so students, researchers, and professionals can verify the math.
