Accuracy Policy

1. Precision & Rounding Rules

Computers compute using binary floating-point representation, which can introduce microscopic rounding errors (e.g., 0.1 + 0.2 = 0.30000000000000004). To prevent these from appearing in the user interface, we enforce standard representation guidelines:

• Financial: Rounded to two decimal places (e.g., $100.52) or formatted to nearest integer where appropriate. Intermediate steps retain raw precision.
• Scientific & Engineering: Formatted dynamically based on standard precision criteria or scientific notation when values are extremely small or large.
• Astrology & Numerology: Computed based on strict integer arithmetic or modular loops to ensure no rounding affects zodiac boundary calculations.

2. Unit Conversion Standards

Many calculators accept multiple units (e.g., metric vs. imperial for health metrics, or annual vs. monthly frequencies in finance). We normalize all user inputs to base units (e.g., meters, kilograms, annual percentages) prior to executing pure calculation functions. Once computed, values are formatted back to the user's preferred units for rendering.

3. Validation Rules

Every calculator form has built-in input limits (minimums and maximums) to prevent numerical overflows, division-by-zero errors, and negative value entries where they are mathematically invalid. If a user inputs an out-of-range value, clear validation warnings are displayed inline, and calculation execution is paused until valid inputs are provided.

4. Disclaimer & Limitations

While every effort is made to maintain mathematical correctness, calculations are approximations. They should not be relied upon for legal, financial, or medical decisions. Please read our complete Disclaimer for details.
