Unit 9 Roman Numerals in Nemeth Code
Roman numerals used in literary text, such as numbering front pages, follow UEB rules for placement of the grade 1 indicator and capitalization of letters.
When Roman numerals appear in a mathematical expression or between Nemeth Code switch indicators, the English Language Indicator (ELI) and Nemeth rules for capitalization and punctuation are followed. A Roman numeral is considered one number regardless of the number of letters it contains.
In Nemeth code, an ELI is required:
1) before all lowercase Roman numerals that are preceded and followed by a space or punctuation symbol.
* Note: because a Roman numeral is considered one number regardless of the letters it contains, only one ELI is used at the beginning of the number.
Example:
| ⠰⠊ | ⠰⠊⠊ | ⠰⠊⠊⠊ | ⠰⠊⠧ | ⠰⠧ | ⠰⠧⠊ | ⠰⠧⠊⠊ | ⠰⠧⠊⠊⠊ | ⠰⠊⠭ | ⠰⠭ |
| i | ii | iii | iv | v | vi | vii | viii | ix | x |
2) before all capital single letter Roman numerals.
Example:
| ⠰⠠⠊ | ⠰⠠⠧ | ⠰⠠⠭ | ⠰⠠⠇ | ⠰⠠⠉ | ⠰⠠⠙ | ⠰⠠⠍ |
| I | V | X | L | C | D | M |
In Nemeth code, an ELI is NOT required if:
1) the a Roman numeral consists of two or more capital letters.
* Note: because a Roman numeral is considered one number regardless of the letters it contains, a double capital letter indicator is used to capitalize multi-letter Roman numerals.
Example:
| ⠠⠠⠊⠊ | ⠠⠠⠊⠊⠊ | ⠠⠠⠊⠧ | ⠠⠠⠧⠊ | ⠠⠠⠧⠊⠊ | ⠠⠠⠧⠊⠊⠊ | ⠠⠠⠊⠭ |
| II | III | IV | VI | VII | VIII | IX |
2) The Roman numeral is entirely enclosed in a pair of grouping symbols.
Examples:
(iii)
⠷⠊⠊⠊⠾
(X)
⠷⠠⠭⠾
3) The Roman numeral is preceded or followed by a sign of comparison.
Examples:
X < C
⠠⠭⠀⠐⠅⠀⠠⠉
m = 1,000
⠍⠀⠨⠅⠀⠼⠂⠠⠴⠴⠴
4) The Roman numeral occurs in an unspaced sequence of terms.
Examples:
x-vi = iv
⠭⠤⠧⠊⠀⠨⠅⠀⠊⠧
C-X(V)+L
⠠⠉⠤⠠⠭⠷⠠⠧⠾⠬⠠⠇
Roman Numerals as Identifiers
When Roman numerals are used as identifiers (numbering for lists, etc.), Nemeth Code rules for punctuating numbers apply. The punctuation indicator is required before a sign of punctuation.
Examples:
i.
⠰⠊⠸⠲
vi)
⠰⠧⠊⠾
(vi)
⠷⠧⠊⠾
I.
⠰⠠⠊⠸⠲
IV.
⠠⠠⠊⠧⠸⠲
(III)
⠷⠠⠠⠊⠊⠊⠾
XX)
⠠⠠⠭⠭⠾
Code Switch Indicators
Nemeth Code Roman numerals appear between Nemeth Code switch indicators.
(The following examples include Nemeth Code switching.)
Examples:
Determine if M > DCC or if M < DCC.
