Frequently Asked Questions
What precision does the Number To Roman preserve?
Numeric conversions use IEEE 754 double-precision (15-17 significant decimal digits). Lossless integer conversions remain exact up to 2^53. For exact decimal arithmetic on very large or very small values, use a server-side BigDecimal or arbitrary-precision library.
What's the supported input range?
The converter handles the full range allowed by the source format's specification. Values outside that range (e.g., negative durations, out-of-spec characters) are rejected with an error rather than silently truncated. Check the input format docs for exact limits.
Can I convert in both directions?
Yes. The converter is bidirectional: switch the source and target fields to reverse the conversion. Round-trip conversions are exact for lossless format pairs and approximate (with documented precision) for lossy ones.
