Question

I have a function to convert string to number

<cffunction name="convertToNumber" returntype="numeric">
    <cfargument name="separator" required="Yes" type="string" />
    <cfargument name="number" required="Yes" type="string" />

    <cfset LOCAL.arrSeparator = ["comma", "period", "lakh_crore"] />

    <cfif ARGUMENTS.separator eq "comma" or ARGUMENTS.separator eq "lakh_crore">
        <cfif ListLen(ARGUMENTS.number, ".") eq 2>
            <cfset LOCAL.integral = ListFirst(ARGUMENTS.number, ".") />
            <cfset LOCAL.fractional = ListLast(ARGUMENTS.number, ".") />
        <cfelse>
            <cfset LOCAL.integral = ARGUMENTS.number />
            <cfset LOCAL.fractional = "" />
        </cfif>

        <cfset LOCAL.integral = Replace(LOCAL.integral, ",", "", "ALL") />
        <cfset LOCAL.returnValue = LOCAL.integral />

        <cfif Len(Trim(LOCAL.fractional))>
            <cfset LOCAL.returnValue &= "." & LOCAL.fractional />
        </cfif>
    </cfif>

    <cfif ARGUMENTS.separator eq "period">
        <cfif ListLen(ARGUMENTS.number, ",") eq 2>
            <cfset LOCAL.integral = ListFirst(ARGUMENTS.number, ",") />
            <cfset LOCAL.fractional = ListLast(ARGUMENTS.number, ",") />
        <cfelse>
            <cfset LOCAL.integral = ARGUMENTS.number />
            <cfset LOCAL.fractional = "" />
        </cfif>

        <cfset LOCAL.integral = Replace(LOCAL.integral, ".", "", "ALL") />
        <cfset LOCAL.returnValue = LOCAL.integral />

        <cfif Len(Trim(LOCAL.fractional))>
            <cfset LOCAL.returnValue &= "." & LOCAL.fractional />
        </cfif>
    </cfif>

    <cfreturn LOCAL.returnValue />

</cffunction>

<cfset separatorNumber = StructNew() />
<cfset separatorNumber.comma = "1,234,567,890.123456">
<cfset separatorNumber.period = "1.234.567.890,123456">
<cfset separatorNumber.lakh_crore = "1,23,45,67,890.123456">

<cfloop collection="#separatorNumber#" item="separator">
    <p>
        #separator# :
        <input type="Text" value="#convertToNumber(separator, separatorNumber[separator])#">
        Length : #Len(convertToNumber(separator, separatorNumber[separator]))#
    </p>
</cfloop>

the length is 17, but in the input text it add extra white space at first char. I really don’t know how to remove the extra white space, and when I add ToString(Trim())

<input type="Text" value="#ToString(Trim(convertToNumber(separator, separatorNumber[separator])))#">

it still have extra white space

thank you

Have you tried to added output="false" to your function tag?

<cffunction name="convertToNumber" returntype="numeric" output="false">...</cffunction>

Hope that helps.
