FAQ
What range is supported?
This converter supports standard Roman numerals for integers from 1 to 3999.
Why is IC invalid for 99?
Standard notation uses XCIX for 99. I can subtract only from V or X, so IC is rejected.
Are overlines for 5000 and larger supported?
No. This page keeps the common school and reference range of 1 to 3999.
