CFLOOP with doubles - Coldfusion

I am trying to use cfloop to loop form 0.0 to 5.0 but it takes out the decimal point and is looping from 0 to 5 instead.

This is my code

<select name="cweight">

    <option value="">---</option>

    <cfloop index = "cweight" from = "0.0" to = "5.0"> 
        <option value="#cweightid#">#cweight#</option>
    </cfloop>

</select>

I need the loop to go over 0.1,0.2,0.3 until it reaches 5.0.

What should I add to allow me to do this?

Solution

  • CF doesn't have "doubles" - numbers have decimal places when they need them.

    To do what you want, use NumberFormat with the mask set to 0.0 so that you always get a decimal place.

    To increment by 0.1 at a time, simply set the cfloop step attribute.

    <cfloop index="cweight" from="0" to="5" step="0.1"> 
    <option value="#cweight#">#NumberFormat( cweight ,'0.0' )#</option>
</cfloop>
