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.
