LSIsNumeric

Synopsis

                  LSIsNumeric(string)

Functions identically to the IsNumeric( ) function within the context of the current locale. Returns true if string can be converted to a number in the current locale or false if it can’t. Here’s an example that determines whether the supplied values are valid numbers for each locale:

<cfloop index="locale" list="#Server.Coldfusion.SupportedLocales#">
  <cfset SetLocale(locale)>
  <cfoutput>
    <p><b>#locale#</b><br>
    -1: #LSIsNumeric(-1)#<br>
    0: #LSIsNumeric(0)#<br>
    1234: #LSIsNumeric(1234)#<br>
    1,234,567,890: #LSIsNumeric('1,234,567,890')#<br>
    $1234.99: #LSIsNumeric('$1234.99')#<br>
    04/15/2003: #LSIsNumeric('04/15/2003')#<br>
    7pm: #LSIsNumeric('7pm')#<br>
    abcdef: #LSIsNumeric('abcdef')#<br>
    true: #LSIsNumeric(true)#<br>
    false: #LSIsNumeric(false)#<br>
    yes: #LSIsNumeric('yes')#<br>
    no: #LSIsNumeric('no')#<br>
  </cfoutput>
