Last update:
May 18, 2026
Description
Determines whether a string is a valid representation of a currency amount in the current locale.
Returns
True, if the parameter is formatted as a valid currency amount, including the appropriate currency indicator. The return value is True for amounts in the local, international, or none currency formats.
Category
Syntax
LSIsCurrency(currency [, locale])See also
History
ColdFusion (2018 release): Introduced named parameters.
ColdFusion 8: Added the locale parameter.
ColdFusion MX: Changed formatting behavior: this function might return a different result than in earlier releases. This function uses Java standard locale formatting rules on all platforms; the results might vary depending upon the JVM; for example, Sun JVM 1.4.1 requires euro format the local currency if the current locale's country belongs to the Euro Zone.
Parameters
Parameter | Description |
currency | A currency string or a variable that contains one. |
locale | Locale to use instead of the locale of the page when processing the function |
Usage
For examples of ColdFusion code and output that shows differences between earlier ColdFusion releases and ColdFusion MX in accepting input formats and displaying output, see LSCurrencyFormat.
Note:
If the locale belongs to a Euro zone country and the currency is a correctly formatted euro value for the locale, this function returns True for all JVMs, including Sun 1.3.1. As a result, with 1.3.1-compliant JVMs, the LSIsCurrency function does not ensure that LSParseCurrency returns a value. If a currency uses the older country-specific format for Euro Zone locales, the LSIsCurrency function returns False for newer JVMs, such as Sun 1.4.1 and 1.6, and True for older JVMs, such as Sun 1.3.1.
Note:
To set the default display format of date, time, number, and currency values, use the SetLocale function.
Example
<cfscript>
currency="$100000"
locale=getLocale()
writeOutput("Locale is: " & locale & "<br/>")
writeOutput(LSISCurrency(currency,locale))
</cfscript>Output
Locale is: English (US)
