History

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

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 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

<h3>LSIsCurrency Example</h3>

<cfif IsDefined("FORM.locale")>
<!--- if locale is defined, set locale to that entry --->
<cfset NewLocale = SetLocale(FORM.locale)>

<p>Is the value "<cfoutput>#FORM.myValue#</cfoutput>" 
a proper currency value for <cfoutput>#GetLocale()#</cfoutput>?
<p>Answer: <cfoutput>#LSIsCurrency(FORM.myValue)#</cfoutput>
</cfif>
