<!-- so "exponent" is not the formal ISO word for this? -->
The 2008 (7th) edition of ISO&nbsp;4217 says the following about minor units of currency:
{{blockquote|Requirements sometimes arise for values to be expressed in terms of minor units of currency. When this occurs, it is necessary to know the decimal relationship that exists between the currency concerned and its minor unit. This information has therefore been included in this International Standard and is shown in the column headed "Minor unit" in Tables A.1 and A.2; "0" means that there is no minor unit for that currency, whereas "1", "2" and "3" signify a ratio of 10:1, 100:1 and {{val|1000}}:1 respectively. The names of the minor units are not given.}}

Examples for the ratios of {{val|100}}:1 and {{val|1000}}:1 include the United States dollar and the [[Bahraini dinar]], for which the column headed "Minor unit" shows&nbsp;"2" and "3", respectively. {{as of|2021}}, two currencies have non-decimal ratios, the [[Mauritanian ouguiya]] and the [[Malagasy ariary]]; in both cases the ratio is 5:1. For these, the "Minor unit" column shows the number&nbsp;"2". Some currencies, such as the [[Burundian franc]], do not in practice have any minor currency unit at all. These show the number&nbsp;"0", as with currencies whose minor units are unused due to negligible value.{{Citation needed|date=September 2020|reason=Second half of sentence is not in above quote.}}

=== Code position in amount formatting {{anchor|codeposition|PositionOfIso4217CodeInAmounts}} ===
The ISO standard does not regulate either the spacing, prefixing or suffixing in usage of currency codes. The [[style guide]] of the [[European Union]]'s Publication Office declares that, for texts issued by or through the Commission in [[English language in England|English]], [[Irish language|Irish]], [[Latvian language|Latvian]], and [[Maltese language|Maltese]], the ISO&nbsp;4217 code is to be followed by a "hard space" ([[non-breaking space]]) and the amount:<ref>{{cite book |chapter-url=http://publications.europa.eu/code/en/en-370303.htm#position |title=Interinstitutional style guide |chapter=7.3.3.

:''a sum of EUR&nbsp;30'' 
and for texts in [[Bulgarian language|Bulgarian]], [[Croatian language|Croatian]], [[Czech language|Czech]], [[Danish language|Danish]], [[Dutch language|Dutch]], [[Estonian language|Estonian]], [[Finnish language|Finnish]], [[French language|French]], [[German language|German]], [[Greek language|Greek]], [[Hungarian language|Hungarian]], [[Italian language|Italian]], [[Lithuanian language|Lithuanian]], [[Polish language|Polish]], [[Portuguese language|Portuguese]], [[Romanian language|Romanian]], [[Slovak language|Slovak]], [[Slovene language|Slovene]], [[Spanish language|Spanish]], and [[Swedish language|Swedish]] the order is reversed; the amount is followed by a non-breaking space and the ISO&nbsp;4217 code:
:''une somme de 30&nbsp;EUR''
As illustrated, the order is determined not by the currency but by the native language of the document context.

===USD, USN: two US currency codes===
The [[US dollar]] has two codes assigned: USD and USN ("US&nbsp;dollar next day"{{definition needed|date=April 2025}}). The USS (same day) code is not in use any longer, and was removed from the list of active ISO&nbsp;4217 codes in March 2014.
